It was the early day in Retroville. At the Neutron household Hugh was in the front hallway directly in front of the stairs. There were four suit cases in front of him. Hugh prepared to start lifting the largest of the four when Judy walked up. She looked at Hugh disapprovingly and spoke up stopping him.

"Oh no you don't, Mister muscles! If you hurt your back lifting those, you'll be no use to me tonight on our third honeymoon when I want all the hotel room furniture rearranged. Hmm hmm." Judy told Hugh as the twins and Goddard walked up. Jimmy, Penelope and Goddard stood by the front of the stairs watching the two. "Don't couples usually go on second honeymoons?" Jimmy asked looking a little confused. "We had one of those, but thanks to a certain young genius and his "Forgetto-Blaster" it was wiped out of our brains." Judy replied. "Oh yeah." Jimmy said remembering the mishap the invention caused. "Along with the entire fifth year of our marriage." Judy added.

"I do wish I could remember that year, eh do you think I had pie?" Hugh asked turning to his wife. Judy unsure how to answer just shot Hugh a look. Minutes later Hugh along with the twins and Goddard were standing outside by the car. With everything needed for the trip all packed and ready Hugh closed the trunk. Hugh turned to face his children.

"Alright Jimbo, Penel, now listen we're gonna be staying at Wild Animal Land, in the Dead Zebra Carcass Suite." Hugh said a little softly. "Don't tell your mother! It's gonna be a big surprise." Hugh whispered while he leaned down a little. Not long after saying this Judy walked up causing Hugh to quickly stand up straight. Judy turned her attention to the twins not noticing Hugh miming a throat-cutting action. "Oh and Jimmy, Penelope Granny Neutron's coming over while we're gone." Judy told her children.

The twins almost couldn't believe their ears. Not that they didn't enjoy Granny Neutron's company, but it felt odd having someone babysit them given their current age. "Uagh Mo-o-om! Don't you remember my theorem proving mathematically we don't need anyone to watch us?" Jimmy cried. "Oh Jim-Jam, Penny, she's not watching you two, you're both watching her." said Hugh. "We're watching Granny?" Penelope asked looking a little perplexed.

"Besides you guys can keep each other company! Now, remember we're counting on you two to watch out for her." said Judy. "Oh and don't conduct any more experiments on her Jimbo." Hugh told Jimmy. "At her age the last thing you want is excitement." Judy added. Not long after Judy said this a noise that sounded like screeching tires was heard not too far from the house. The next thing they knew a taxi cab was hurtling down the street and careened to a stop by the curb.

An elderly woman wearing a long sleeved green dress and a pair of glasses sat in the drivers seat. This was Granny Neutron. A man sat in the back of the cab frozen in a silent scream clutching his heart. This was clearly the cabbie. "Told ya I could get here from the airport in under fifty cents! Hahahahaa." Granny Neutron told the cabbie.

Granny Neutron exited the cab popping the trunk as she did. "Mom!" Hugh said cheerfully. "Oh mother Neutron!" Judy said politely. "Hi granny." Jimmy and Penelope greeted. Granny Neutron slowly hobbled over to them.

"Jimmy, you tote my clothes." Granny Neutron said while handing Jimmy her handbag. "Hugh, you carry my pills, syrups, salves, serums, girdles, ointments, medical devices-" Granny Neutron told Hugh as she walked towards the house. Hugh looked over at the taxi's trunk and saw it was filled with numerous bags. "Trade you." Hugh said quietly as he took the handbag from Jimmy. "And miscellaneous supports." said Granny Neutron.

A little later once all of Granny Neutron's belongings were unloaded Hugh and Judy got into the car and drove off. As they made their way to their honeymoon destination Judy feeling a little concerned spoke up. "Hugh darling, do you think Jimmy and Penelope will be able to take care of granny alright?" Judy asked her husband. "I wouldn't worry about that sugar. I'm sure she can keep Jimmy and Penelope entertained with one of her exciting stories." Hugh reassured his wife. As Hugh said this he didn't notice the two cars that veered to the side to avoid him while he drove down an intersection.

Back with Jimmy, Penelope, Goddard and Granny Neutron the four were all sitting in the living room. Granny Neutron was talking to the twins. Jimmy and Penelope however were not enjoying the conversation. "-And by the time they cleaned out both my ears, there was enough wax to open a candle shop." Granny Neutron told the twins. Jimmy and Penelope stared with looks of disgust on their faces.

Unfortunately Granny Neutron not realizing she was grossing them out continued on. "And then they found this hair that they think might go right through to my foot." said Granny Neutron. To prove this Granny Neutron grabbed the hair in her ear then started tugging on it. Her foot lifted and fell as she tugged the hair a couple times. Jimmy and Penelope's mouths fell open in horror as they watched.

Sometime later the twins and Goddard were down in Jimmy's lab. Jimmy sat in his computer chair. The three watched the computer monitor. "Granny Neutron talks about such weird and disgusting things." said Penelope. "I agree." Jimmy replied.

"Age is a cruel cruel thing, Goddard. In a short sixty-five years you completely lose your ability to tell when people want you to stop talking." said Jimmy. Displayed on the monitor was live feed of Granny Neutron sitting in the living room talking to cardboard cutouts of Jimmy and Penelope thinking the cutouts were her real grandchildren. "And forget preparation H! I made it all the way to preparation X! Hahahaha." Granny Neutron said with a chuckle. Penelope made a disgusted face. Jimmy thought for a moment then his face brightened up as he came up with an idea.

"Wait a minute! If I made her young again I bet she'd stop complaining. Ugh, but I promised mom and dad I wouldn't experiment on Granny." said Jimmy. "Especially after that time I made her magnetic." Jimmy added with a chuckle. Penelope snickered as she and Jimmy thought about the mishap.*Flashback* Granny Neutron stood on the sidewalk with her luggage. She waved goodbye to Hugh, Judy and the twins who were all standing on the front porch waving back.

"Bye-bye I had a wonderful tiiiiiiii-!" Granny Neutron was saying, but was cut off. A bus drove by the next thing Granny Neutron went flying towards it and she clung to the back of the vehicle splayed on it like a fridge magnet. *End of Flashback* Jimmy having come to a decision got to work. Sometime later the twins were standing in front of a table. On the table were a series of test tubes and beakers filled with fluids that boiled and frothed.

One test tube was full of a green fluid. This was in fact an anti-aging tonic. Jimmy and Penelope both waited patiently for the solution to finish. There was a dinging noise and the words solution complete appeared on the computer monitor. Jimmy smiled and carefully grabbed the tube.

"She's awfully old, I hope this is enough." said Jimmy. Penelope gave her brother a thumb up. With the tonic ready they left the lab and headed back up into the house. The twins and Goddard walked into the living room. Granny Neutron was sitting on one of the chairs struggling to open a bottle.

The lid creaked as the twins walked up to her. Jimmy made sure to hide the tonic behind his back so Granny Neutron wouldn't see it. Granny Neutron stopped what she was doing when she noticed her grandchildren. "Ah- good morning, I was just telling you two over there about my old deviated spatchum on cold mornings it rattles like a tin man throwing up a hoagie full of wood screws." said Granny Neutron. "What's in the bottle?" Jimmy asked.

"Tongue De-Furrer." Granny Neutron replied. Jimmy and Penelope grimaced. "Your tongue gets furry when your old. Sometimes I wake up and the cat's chewing on it." Granny Neutron continued. "Oh, let me open that for you." Jimmy offered. Granny Neutron handed Jimmy the bottle.

Jimmy turned his back so Granny Neutron wouldn't see what he was about to do. He popped the cap off the bottle and quickly poured the tonic into the de-furrer. Jimmy turned to face Granny Neutron. "I think you'll feel much better and quieter after you drink this." Jimmy told Granny Neutron as he handed her the bottle. Granny put the bottle to her lips and gulped down the contents.

Once she finished she smacked her lips as if she had just tasted something awful. "Tastes funny. Of course, what do I know- after sixty your sense of taste completely disa-" Granny Neutron said before she was cut off. There was a flash of light that completely enveloped Granny Neutron. Once it faded there was a baby with hardly any hair and wearing a diaper sitting in the chair. Jimmy and Penelope's eyes widened in shock.

"Granny?!" the twins cried in unison. "Goo-goo-gah-geee." Granny Neutron or Granny baby replied. "Uh-oh Granny?" Jimmy asked concerned. "I feel great! Did I just take my morphine?" said Granny baby. Penelope stared surprised that their grandmother was still able to talk, but it was very clear that the tonic was unstable.

And instead of changing Granny Neutron into a young lady she had turned into a baby. Penelope's face paled. She did not want to imagine how their parents would react if they found out. "U-uh no Granny you're uh well you're sort of ah- baby." Jimmy explained. He smiled sheepishly at Granny Neutron as Goddard pulled out a mirror for her to see her reflection.

"Holy fiber caps! I'm topless!" Granny baby cried frantically trying to cover herself. "Ooh man! This isn't good." Jimmy groaned. Jimmy looked at Granny baby and noticed she was wearing a diaper. "Where'd you get the diaper?" Jimmy asked confused. "I was already wearing it." Granny baby replied.

Not long after saying this there was a fart noise and a foul smell started to emit from Granny baby's diaper. "Ooohp I need my diddie changed!" Granny baby cried. "Oh yuck!" Penelope grimaced as she pinched her nose. Goddard retracted the mirror as Jimmy tried to think unsure of what to do. "Problem..." said Jimmy.

Jimmy turned to Goddard hoping he'd be able to help. "Goddard! Change diaper." Jimmy ordered. The mechanical canine gagged disgusted. "Change me NOW! Waaaaa!" Granny baby whined. There was another fart noise.

Jimmy panicking turned back to Goddard. "Who can change a diaper?" Jimmy asked. Goddard's chest opened up revealing his monitor. Goddard began to display options. 'A Nurse' " I don't know any nurses." said Jimmy.

Goddard displayed another option. 'Your Mother' "No way. I love and respect Mom far too much to let her know, I, disobeyed her." Jimmy told Goddard. Goddard displayed one more option. 'Cindy' Jimmy's jaw dropped for a moment. Jimmy and Penelope both turned their heads to look out the window. Cindy was across the street with Libby in the driveway of her house.

They could also make out a table along with racks of clothes, boxes and other items. It didn't take a genius to figure out they were managing a garage sale. "Uh-uh, no way! I will never ever ask Cindy for a favor!" Jimmy yelled as he turned back to Goddard. Once again there was a farting sound. "Clean my poopy!" Granny baby sobbed.

"I don't think you have much of a choice!" Penelope said with her nose pinched. Jimmy knew his twin was right. "Okay, let's go ask Cindy for a favor. Shall we?" said Jimmy. With that the four made their way over to Cindy's house. Over at the Vortex residence Libby stood at the folding table she and Cindy were using.

Cindy walked up to her friend. "So how much have we collected so far Libby? I'm starving!" Cindy said putting her hands to her stomach. Libby looked at the small metal box in front of her counting the money inside of it. "We're a dollar and twenty-three cents away from just enough to split an enchalaparitto from Taco Horn." Libby told Cindy. The two girls smiled at the thought.

A cardboard box behind them started to rattle and jump. "Hey! Hey! Oh wow!" Sheen's muffled voice came from the box. Cindy and Libby turned their attention to the box. Sheen stood up inside the box he had been rummaging through with a bra in hand. "This must be a discontinued Ultra Lord double barrel slingshot!" Sheen cried excitedly.

Sheen clearly didn't know what the item was. Cindy shook her head. She and Libby smirked as this gave them an idea. "Uh, sure, ten bucks." Cindy told Sheen. "I don- alright deal." said Sheen.

"Uh I don't know Sheen if that's what that is then my mom has a lot of Ultra Lord double barrel slingshots." said Carl. Sheen on the other hand was a little occupied with examining the item as he spoke. Sheen turned to look at Cindy. "Do you have any other Ultra Lord collectables?" Sheen asked. "No, pay and leave." Cindy replied.

"Any Ultra Lord videos?" Sheen asked. "No." said Cindy. Unfortunately Sheen wasn't letting up. "DVD's?" "No" "Cd Rom?" "No!" "TV episode memorabilia?" "No!" "What about those discolored pajamas you get at the swap meet?" the two said back and forth. "No. Do I look like the kind of pathetic self-deluded dweeb-case who'd have any Ultra Lord anything?" Cindy snapped.

She was clearly annoyed and probably even a little stressed. Sheen took a breath before speaking. "No, you look like the regular kind of self-deluded dweeb-case." Sheen replied. Carl and Sheen both burst into laughter and did a fist bump. The twins walked up.

Carl and Sheen noticing their friends decided to greet them. "Hey Jimmy! Penelope!" said Carl. "Hey what's up Jim, Penelope." Sheen greeted. Jimmy waved at them with a nervous look on his face. Penelope waved as well, but her face was a little pale.

Cindy scowled at the twins. "What are you two doing here?" Cindy asked. "Fine, thank you. So, say! Great stuff! Aaauum, I was wondering where your mom is." Jimmy said as politely as possible. "Why?" Cindy inquired. "Well uh- well here's the thing. I need some help with- uh- this." said Jimmy.

Goddard walked out from behind Jimmy and Penelope with Granny baby strapped to his back while Jimmy gestured to her as he gritted his teeth. "Aaaawh!" said Cindy and Libby. The two giggled, but stopped when they got a whiff of the foul odor coming from Granny baby's diaper. "Ewwwwww! Ahhhhhhhhgh!" Cindy and Libby cried. The two waved their hands in front of their faces and plugged their noses trying to keep the foul smell away.

"Yeah- See- I-I think she might need changing." said Jimmy. "What was your first clue?" Libby asked as she kept her nose pinched. "So you'll do it?" Jimmy asked looking at Cindy. "As much as I detest helping smug pseudo-brainiacs, my nurturing female instincts will not leave a helpless infant in your care." Cindy replied. "Where's the new diaper?" Cindy asked.

"New diaper? What's wrong with the one she's wearing?" Jimmy asked a little perplexed. Cindy stared at Jimmy with a look of utter disbelief. "It's full of POO! I thought you were a genius!" Cindy yelled. "Hey he's a guy. Hahahahaaa." Granny baby said with a laugh. Cindy and Libby gasped their eyes widening as they did.

"S-S-She talked?" Libby said shocked. "Well now that we got past that! I've got a rash brewing down here that would make a red-hot chili pepper look pale!" said Granny baby. "Ehhh that is just disgusting." Penelope grimaced. "Cindy, Libby- Uhm, Granny Neutron." Jimmy introduced feeling a little awkward as he did. "You turned your own grandmother into a baby?" Cindy cried.

"I-I have a loophole, I-I mean an explanation! This could have happened to anyone with a genius IQ and access to unstable chemicals!" Jimmy explained. "Could we hurry up? I'm getting dizzy from my own fumes here." Granny baby complained. Granny baby noticed an old pull string rag doll on the table. "Oh dolly!" Granny baby said clearly interested in the toy. Cindy picked the doll up and walked up to Granny baby.

"How long is she gonna be a baby?" Cindy asked as she handed the doll to Granny baby. "Well I'm not sure exactly, but I've gotta change her back before mom and dad get home." Jimmy explained. "Well how many diapers do we need?" Cindy asked. A loud farting noise broke through the air. "Well I'd err on the side of hundreds." Granny baby pipped in.

"So great!" said Jimmy. He pulled a paper and some money out of his pockets. "So here's some money and a list of things I need for the antidote, I'll see you when you get back from the store. Thanks!" Jimmy told Cindy. "Oh no you don't." Cindy said glaring at Jimmy. She turned to look at Libby.

"Libby you run the yard sale while Doctor Spock, the giant and I go to the shop." Cindy told her friend. "That's fine by me." Libby replied with her nose still pinched. Penelope couldn't blame Libby for not wanting to be anywhere near Granny baby and her stinky diaper. As they started walking away Penelope noticed Carl and Sheen goofing off in one of the boxes and couldn't help, but snicker at how silly her friends were being. Later after making it to the store with Cindy's help they managed to change Granny baby's diaper.

They couldn't leave the store just yet. Jimmy still needed to get the things needed to restore Granny baby to her proper age. The five were now currently in one of the aisles. While Jimmy was grabbing the things he needed off the shelves Cindy and Penelope watched Granny baby. Penelope could tell from the look on Cindy's face she was bored.

"I'm bored! Make a funny face and let me hit you with my rattle." said Granny baby. "No." Cindy said flatly. Granny baby started crying loudly. Cindy and Penelope covered their ears in pain. "Okay, okay." said Cindy.

"Bleah." Cindy said as she made a face. Granny baby whacked Cindy in the face with her rattle. "It's fun hitting you hahahaa." Granny baby said with a laugh. "Granny, Granny quiet." Jimmy told her a little softly. A random man having heard looked at the children.

"D-did that baby just talk?" the man asked. "No! Ha ha. Everyone knows babies can't talk." Jimmy replied. "Yeah that would be crazy!" Penelope added. "That's right cos, if we could the Videotubbies, be canceled so quick it'd make their head aerials spin." Granny baby said laughing at the end of her sentence. Jimmy, Penelope and Cindy looked apprehensive.

All the adults that witnessed gasped in amazement. "Jimmy let's grab the stuff, pay and run." Penelope whispered to her twin. Jimmy didn't need Penelope to tell him twice. Moments later Jimmy, Penelope, Cindy and Goddard carrying Granny baby were running down the streets away from a clamoring mob of people. "Luckily I've got thirty-six hours to make the antidote before our parents return." Jimmy said as they kept running.

As soon as Jimmy said this his cell phone started ringing. Jimmy quickly pulled his phone out and answered it. 'Please don't be Mom or Dad!' Penelope thought. "Hello." said Jimmy. Meanwhile back with Hugh and Judy the two were in the car driving down the road.

"Honey it's mom, we're coming home." said Judy after Jimmy answered his phone. "No! I mean, oh great! I mean-oh why?" Jimmy cried trying to hide his distress. "Well your father accidentally disturbed a nest and had a run-in with a mother eagle." Judy explained frowning as she did. Hugh who was driving looked up a little fearfully at an eagle perched on the top of his head. "How's Granny?" Judy asked.

Back with the twins and co. they were still running from the rapid mob. "Oh she's great, yeah, you wouldn't even, recognize her." Jimmy replied. "Oh well I'm very proud of you Jimmy, we'll see you, Penelope and granny soon buh-bye." said Judy. "Wait, wait, wait, mo-mom." said Jimmy. Judy ended the call.

Back with Hugh and Judy Hugh was desperately trying to talk to the eagle on his head. "Euh-Really. I wasn't trying to harm your little eaglets I wa-" Hugh was saying before Judy cut him off. "Stop talking to it Hugh." Judy told him. "I think it calms her." said Hugh.

The eagle chirped and squawked. "Try moving your finger like a worm." Hugh told Judy a little softly. "No." Judy said flatly. Back with the twins, Cindy, Goddard and Granny baby the mob had followed them all the way back to the Neutron house. The mob was gathered outside by one of the windows while Jimmy was throwing the ingredients from the store into beakers on the coffee table.

Cindy and Penelope looked out the window in fear. "We want the talking baby! We want the talking baby!" the mob chanted. Jimmy knowing they were pressed for time turned to Goddard. "Goddard! Compare antidote completion with mother's return time! Go!" Jimmy commanded. Goddard's chest opened displaying his monitor.

Displayed on the monitor was live feed of Hugh and Judy in the car driving down the road. A timer was counting down from 59 revealing they had a very short amount of time to finish the antidote administer it to Granny baby and somehow get rid of the mob. "Oh mom and dad!" Jimmy cried. "Uh come on, think, think, think!" said Jimmy as he closed his eyes and began to think hard. Remembering when Granny baby had the doll from Cindy and Libby's garage sale Jimmy quickly came up with an idea.

"Brain Blast." Jimmy cried. "Okay as soon as it turns blue pour it in a baby bottle and meet me outside!" Jimmy said he ran up to Cindy and handed her the test tube he was holding. "Come one Granny!" said Jimmy. Jimmy, Goddard and Granny baby left the living room. Cindy was confused, but Penelope had an idea of what her brother was going to do.

Jimmy opened the front door. "Ladies and gentlemen, I give you the amazing talking baby!" Jimmy said as he stepped out. He held Granny baby in his arms for the crowd to see. "Oooooh!" the crowd said in awe. On cue Jimmy pulled a talking doll pull string he rigged to Granny baby's back making sure the crowd would be able to see it.

"Give me a cuddle. And a diaper change while you're at it. Ah-hahaha-ha!" Granny baby said with a chuckle. Jimmy grinned at the crowd. "Hey-hey! There's a string in her back!" said a random man. "Oh no I have been found out!" Jimmy said in a bad acting voice. "Yes you have son!" said the man.

The crowd grumbled and complained as they started to leave the front yard. Jimmy sighed in relief. Cindy and Penelope walked out. Cindy grudgingly held out a baby bottle filled with the completed antidote. "Here." said Cindy. "Anything else you'd like? Your slippers and a pipe maybe?" Cindy added sarcastically.

Jimmy took the bottle and put it in Granny baby's mouth. Granny baby started gulping down the contents of the bottle. After drinking enough of the antidote Granny baby was enveloped in a light. Once it faded Granny Neutron was standing next to Jimmy returned to her proper age. Not long after there was the sound of a car.

The three turned to see Hugh and Judy pull up into the driveway. "Hello kids, how was everything?" Judy asked. "Oh Hi mom!" Jimmy and Penelope said in unison. Cindy looked at Granny Neutron with slight disbelief. "Uh- nothing unusual here, just me, Penelope and Granny, obeying all your rules, yes ma'am that's what were doing." said Jimmy.

Carl and Sheen walked up onto the lawn. "Hi, Mr. Neutron, that shirts cool, and so is that big bird on your head." Sheen said pointing at Hugh. "It's actually an eagle Sheen, it considers me a hostile predator." Hugh explained. The eagle tapped Hugh's head. Carl and Sheen winced.

"Ooh does that hurt?" Carl asked concerned. "Yes, very much." Hugh replied. Hugh and Judy walked away as the eagle tapped him again with a squawk. 'Hopefully mom can help dad do something about that eagle.' Penelope thought. "I'd love to stay and help you narrowly avoid even more consequences of your stupid actions, but it looks like Libby and I have a date with enchalaparitto's." Cindy told Jimmy.

As Cindy walked away Penelope turned her head to see that the people from earlier were all at the garage sale. Libby was holding a bunch of dollar bills in her hands and she looked excited as the people browsed and purchased things. "It's nice to have you back Granny." said Jimmy. "Yeah." Penelope agreed. "So nice to be back Jimmy, Penelope. Yehahaha." Granny Neutron replied with a laugh.

Carl walked up to them. "Hey Jim, Penelope uh I'm really thirsty does your mom have any lemonade?" Carl asked. "Drink this." said Granny Neutron. She handed Carl the baby bottle containing the antidote. "No!" Jimmy cried.

"Carl don't dri..." Penelope started to shout, but it was too late. Carl gulped down some of the bottles contents. There was a flash of light. When it faded the twins looked at their friend. "Carl? You okay?" Jimmy asked concerned.

Carl was now an old man and resembled an elderly Mr. Wheezer. "Well my eyes hurt, my hair's gone, and I have a powerful urge to dance badly!" said Carl. "I'll take a piece of that!" Granny Neutron cried. A speaker came out of Goddard and started to play old music. Granny Neutron and Old Carl started to dance on the lawn.

"Oh great." said Jimmy. "Now we have another mess to fix." Penelope muttered. "Oh yes! Hehahaha ha! Ha, throw me around!" Granny Neutron said as she danced with Old Carl. The twins walked away knowing Carl was going to need some anti-aging tonic. It would be safe to say Jimmy wouldn't be experimenting on Granny Neutron ever again.

Well how was it? R&R. Tips on what I can do to improve welcome. No flamers please.
