In Abuelita's house, Melody dropped on the nearest couch and exhaled deeply.

"God…I have never been so tired in my entire life!" Melody groaned.

"Same here honey." Soos, exhausted from being on the couch near Melody, joined in.

It took A LOT of effort to put the three alien kids to sleep with how hyperactive they are even with the help of Soos' granny and considering they did this not by turning into their gremlin mood and just in a typical way Kids can suck the energy out of the adults it was an achievement.

"Sweetie? Remember when we talked about having children?" Melody asked his husband.

"Yes?"

"I think we should wait at least 4 years until we know we aren't ready yet."

"No problem dude."

Just when they decided to postpone having children after seeing how truly challenging it is for the time being. Suddenly the sound of something shattering was heard and children woke up.

"SLEEPOVER! YAY!"

Both adults groaned loudly with their heads hitting the back of the couch.

Stan rubbed his eyes very tired and it was very late in the night, since it was dark he had no choice but to accompany the Membranes, Zim and their Skoolmates back to where the rest of the Skoolmates are to his displeasure. The annoying part was that Zim was under house arrest in the Shack but decided to accompany Dib anyway just so he had more time sneering at him which would have led to another inane argument if it were not for Stan giving them dirty eyes.

"Ugh, it's late at night! Why are you two staying until 3 freaking am!? Didn't you learn anything about leaving weirdos alone after dark?" The conman Pines grumbled.

Dib adjusting his glasses protested "I'm not a weirdo! There was…important things to do!"

Gretchen still was looking at Dib with flustered eyes to Gaz's disgust, she did not need to see that.

Zim crossed his arms and made his complaint to the Elder Pines clear "And I am Zim! The greatest warrior in the universe! Your lack of respect for my superiority is… infuriating!"

Stanley rolled his eyes knowing they were just messing around and then somehow ended up singing "Save the drama for your mom, green bean. I just need to get ya kids back before I fall unconscious from sleep deprivation!"

Suddenly, Miss Bitters materializes behind Stan with a menacing shadow and hissed in her usual eerie tone making the Skoolmates a bit tense, except for Keef of course "What's this? A late-night rendezvous with… childish interlopers?" she hissed almost like a snake.

"Great. Just what I wanted in how to end tonight on a high note—a creepy teacher and two losers." Gaz drily commented.

Gretchen stopped herself from crushing for a moment and was visibly sweating in fear.

"I'm really not in the mood for her scaring me into oblivion." The big-headed boy whispered to the disguised Irken.

"Oh, she's far scarier than any Irken Warlord." Zim nervously on one of the rare occasions agreed with his nemesis with a nod.

Conman Pines turns around and practically jumps back upon seeing Miss Bitters so close and almost stuttering "Whoa! Didn't see you there! You, uh…" He got a better look at this demonic hag who then turned on him like a predatory owl that was looking at its prey, he began to understand why the kids called Miss Bitters scary as his mouth became dry. "look… good… at this hour?"

Scary Teacher gave the most ghastly grin the Pines and the Kids had ever seen. She slithers closer to him to his discomfort "Oh. Your rugged exterior is positively delightful in the moonlight."

Stanley tried very hard not to cringe, feeling if he just expressed his facial features wrongly, Miss Bitters would tear his face.

"Wow, Old Man. You've really got a way with the ladies." The Purple-haired Membrane raised an eyebrow, while revolted she was also amused by this turn of events.

Dib and Zim on the other hand exchange horrified glances, each of them wishing they could teleport FAR away from what they were thinking was going on.

Stan tried to excuse himself "M-misss! It's too late at night and I don't wanna bother so I'm just- " Just when he tried to turn away, Miss Bitters once again slithered, blocking his path. She took a step closer and revealed her intentions ambiguously.

"Oh, but why rush? The night is young, and you have so much… potential…"

The Membrane boy definitely did not like where this was going "No, no, no! This is wrong on so many levels!"

Zim, sharing his dismay pointed "Why is that beast attracted to him, Dib Monkey?! He's a mere… dirty man-gorilla!"

"Maybe she has a thing for desperation and expiration." The Membrane girl mockingly added.

The Elder Pines nervously took hold of his collar and gulped "I-I think there's some potential in finding a very, very quick exit! Uh… how about we just get to be friends, huh? Very FAR friends!" He then slowly backed away, not daring to turn his back as if he were facing a tiger.

Miss Bitters, still grinning ghastly, and calls after them said in a haunting sing-song " Come back soon! I have endless time to share, just like all my ex-husbands before they passed away!" she added menacingly and ambiguously.

Stan couldn't take it any more so he did the sensible thing, he ran in a fit of panic "CODE 618!" He shouted and ran very fast.

"We need to leave! Now!" Dib yelled.

Zim grabbed his nemesis and ran "Yes! To safety, away from the terror of morning romance!"

"Yes! Let's go! Before this gets even weirder!" The big-headed boy agreed frantically with the Invader as both made haste.

"We're doomed." Gretchen who also was running sighed.

The only one who didn't run was Keef oblivious of everything and Gaz leaned back, still amused. "Don't forget to send me a postcard from your romantic getaway!" She jeered loudly at the running Pines.

Tomorrow Morning….

Another morning, another typical spat between Zim and Dib who wasted no time about their board game strategies. Soos and Melody today were not here tired from taking care of the triplets so they stayed in Soos' granny's house.

"HA! Dib-Stink, I expected you to expect my expected attack!" Zim gloated.

Dib gloated back "Aha! But I expected you to expect me that I expect you to expect!"

"But I expected you to expect my trap to expect it and expect my expected attack and expecting my counterattack as expc- "

"You guys have issues." The Corduroy girl grunted deadpane cutting him off as she was in the cashier's place with a hand holding her face in boredom. This spatting was entertaining at first but now it was just mildly annoying.

"How dare you cut off Mighty Zim's glorious speech, Greeny Buffalo Check Orangutan!?" Zim growled at Wendy for cutting her off which she responded with an eye roll.

The Membrane boy tried defending his not-so issue "But to defeat my enemy I must study my enemy, then become my enemy, the moving with my enemy, then wear my enemy's clothes, then– "

"We get it, we get it! Stop making it weird!" Gaz snapped at his brother to not make it weird, passed by and smacked his head to not make it weird. The Corduroy girl meanwhile wore a face that said 'Are you serious?' at this eccentricity.

"Zim for once agrees with Dib the stinky, except for the creepy part…" Zim bleached at Dib then continued "And speaking of…GIR!" he loudly called his SIR unit yet no trace of him came "GIR! stop fumbling with whatever Giry thing you are doing!" Yet no answer which made him irritated and confused so he called back again "GIR!"

He called him more yet no sign of him was, later he searched for his minion yet no sign of him. Soon everyone but Gaz joined in realizing this wasn't one of Gir's shenanigans he really had disappeared.

"GIR! GIR! Where are you Gir?? Master promises to reward you with burritos." Zim looked around as he called his minion. "Hmm, strange, that usually works. You Dib Clone Girl! Have I seen my minion?"

"I'm as lost as you Zimmy." Mabel shrugged who was also looking for Gir checking under the table.

"Even weirdly, there is no sign of Minimoose either." Ford who also joined in as well uttered.

"Can't Bug Boy track them down or something? They are your 'Minions' after all." Stan, looking inside of a box asked.

Zim immediately rejected that by insulting him "Foolish Fossilized Gorilla! Of Course, Zim would put a tracker on his own creations! Yet…the tracks don't work which means either those two scrapheaps damaged themselves- knowing Gir it won't be much of a surprise- or…someone has kidnapped them and knew of the trackers." he concluded.

Ford nodded grimly "I was afraid of that, the Shack is filled with security if there was an intruder they would have picked up, I know it because I designed them which means somehow very competent and skilled did so."

That likely speculation sent everyone a bit on edge because whoever it was could have hurt them if wanted to.

"So…what should we do, Great Uncle Ford?" Dipper inquired.

"I called Mcgucket to come, he is an expert on robotics so he would know how to track alien robotic tech. In fact…" Stanford looked at the clock watch of the Shack "He should be here by- "

SLAMMED!

The door suddenly slammed open making everyone but Gaz and Ford startled as they looked back. The non-Fallers didn't know what they expected from this supposed robotic expert, but a hillbilly with a hillbilly accented with a long white beard and green goggles was not that.

"Howdy fellas!" There it was Mcgucket in his all hillbilly glory greeting. Zim was bleached at the sight as he always found human facial hair disgusting and this human had a long bear that reminded him of an alien caterpillar, Gaz raised an eyebrow, Wendy nearly dropped her magazine and Dib was surprised. "You won't believe what I just stumbled upon!"

Stan, without looking up, asked "Let me guess, another 'mysterious' fungus that makes you see visions of pancake donkeys?"

"No, no! This is serious! I found a signal!"

"A signal you say?" Ford was piqued in interest.

"Yeah and- " Fiddlegord stopped what he was saying and stared at Dib oddly and leaned a bit closer "Huh…your head is…small."

"Uhhh, thanks?" The Membrane boy, having no idea how to feel about that, replied.

"Who's the hillbilly?" Gaz inquired.

Dipper was the one who gave a summary as he gestured "That's Mcgucket, He's the local inventor Grunkle Ford talked about."

"Why does the decrepit goat look like a homeless unproductive member of your society?" Zim titled his head, recalling one of his disguises as a homeless man.

That caused the Fallers to wince or glare at Zim with Stan smacking his head.

"Hey!"

And Stanford looked guilty.

"He had uhm an… unfortunate period." The Pines boy elaborates awkwardly.

Gaz nearly snorted if it were not for Mabel and Wendy giving her a look that said 'Don't you dare snort about it!'.

"ANYWAY what was the signal you talked about?" Stanford asked his old friend not wanting to muse on how he had a hand in his friend going on a downtrodden spiral.

"Oh right! I located an indecipherable signal last night! It was identical to one before that raid on the power plant."

Every but Fiddleford then suspiciously looked at the disguised Invader who saw their looks refuted their suspicion "Don't look at Zim, I can't claim credit for it. You put me in house arrest. Besides, why would I kidnap my own minions? And by the way, I am not a kidnapper! I am a conqueror!" the insectoid alien crossed arms in indignation.

Whatever you say, Zim. But if you're involved in this, I'm going to make sure everyone knows." The big-headed Membrane, still suspicious of him, told him that he in response blew a raspberry at him with his worm-like tongue, such a mature reaction from an Elite Invader.

Suddenly Dipper snapped his fingers, recalling something "That's also when the new cryptid was seen after the raid."

"What do you mean partner?" Dib glanced back at Dipper asked.

"Apparently there were first-hand accounts of the sighting of a Wampus Cat stealing machinery and breaking into a power plant stealing energy coils."

"Wasn't that thing supposed to be in Texas?" Dib confused, said.

Mabel snorted "And Unicorns were supposed to be from Europe yet here we have them."

"Unicorns are REAL!?" Dib exclaimed as he turned back to Mabel.

"Yeah, and they are massive jerks." The Pines girl bitterly answered.

Wendy then shrugged "Welp I'm down for some mystery hunting, I'm beginning to get bored. Dipper, you want to team up?"

Dipper brightened up with that "Yeah, I'd love to! But I was hoping Mabel would come too…"

"Aw, I would, but I have plans with my friends to do a "Gnome Fashion Show." It's going to be amazing!" The Pines girl chirped.

" A 'Gnome' Fashion show?" Gaz raised an eyebrow at the Pines girl.

"Yeah, though for some reason they banned Dib from ever coming there."

Gaz gave a knowing look at Dib who awkwardly scratched the back of his head as he nearly vivisected a gnome if it were not for Dipper stopping him.

"Okay, Wendy, let's go check out that Wampus Cat sighting then." The Pines boy responded to the redhead Corduroy.

Stanley clapped his hands and announced the plan "Alright, so here's the plan! McGucket and I will investigate those signals. Dipper and Wendy will track down this Wampus Cat, and Zim and Dib…"

"Wait, why do I have to be stuck with Dib Worm?" Zim hissed in protest.

"I don't want to be stuck with you either, Space Boy!" Dib also shared Zim's displeasure.

The Membrane girl rolled her eyes "You two are going to have to deal with it. And I'm going out alone before either of you idiots blow anything up."

Mabel grinning mischievously offered her a reason to stay "I'll give you Waddles for a day if you supervise them!"

That actually made the purple girl reconsider "Fine. But if the Mystery Hack blows up, I'm not responsible."

"What am I, an insane pyromaniac!?" Dib squawked that he was considered as much of a hazard as Zim.

"Alright, it's settled! McGucket and I will check out the signals, Dipper and Wendy are off to find the Wampus Cat, and Zim and Dib… well, good luck with whatever you're doing." Stanford declared.

"Let's go find that signal!" McGucket announced.

Dipper turned to Wendy "Ready to go?"

"Always!" Wendy eagerly accepted.

And so, everyone left leaving the Membrane siblings and Zim with Dib and Zim not finding each other's company desirable.

"This is going to be the worst day ever." The Invader grumbled.

"Tell me about it. I wanna find the Wampus Cat with my best friend! not be stuck here suffering in your presence!" Dib whined wishing it would have been him instead of Wendy.

"Hey! It is a great honor to be in Almighty Zim's presence!" The Alien objected in indignity and from then they began arguing with each other again while Gaz ignored them and played her Game Slayer, only for the one-hour limit to reach.

"GAH! Dammit Dad!" Gaz cursed her father for putting the damnable time limit on her game and grumbled "This better be worth it…"

" 'It's I ZIM! Behold my magnificence and weep, also roll over 40 times!' "

" 'Oh ah nooo my BEAUTIFUL body! Zim's perfection is sullied and had to suffer a human experience in the bathroom!'"

Both Dipper and Wendy laughed out loud after they respectively mimicked Zim.

"Not that I have a vendetta against the green guy, he's something but MAN he needs to take a chill pill!" The Corduroy girl snorted.

The Pines boy agreed with her "Yeah, though as much as I like Dib he didn't exactly help in him being 'Chillax' either."

"Dude, I don't think I've ever seen a day where they won't bicker at each other like an old married couple." she mused.

The Pines boy snorted with faux horror "Don't let Mabel hear that, she may get ideas on her Shipping obsession."

Wendy chuckled at that "Yeah…God I can't believe Mabel basically drugged Robbie and Tambry into getting together!" She recalled the Love God incident. Dipper told him about the portion later on.

"Good thing the portion only lasts one hour or else I doubt even Grunkle Stan would be leeway about basically violating free will." he exasperated, the whole thing was stupid, though he wasn't the only one sharing that sentiment.

"Yeah, by My ancestral Lumberjack ghost I CAN'T believe I threatened Tambry with violence over dating Robbie of all people!" she gagged spelling the name of her ex "I honestly don't know WHAT I was thinking of dating that edge lord."

Suddenly, Dipper's phone which he bought after the first summer beeped and vibrated in his pocket, he brought it out and saw it was coming from Great Uncle Ford. He accepted the call "Hi? Wait, what's going on?" He asked this time a bit louder as something was interfering which piqued Wendy's interest. Dipper then put on his loud speaker for Wendy to hear it as well as this seemingly concerned her as well.

"Back zzzr- mystery Shack- zzzzzkrrrh attacked!- ZZZGRRR!- "

"We have to go!" Dipper turned to Wendy with a serious face and then both began running fast back to the Shack.

"Well, that was a bust!" Mabel grumbled as he walked back, she checked the 'Gnome Fashion Show' and she was disappointed. Turns out Gnomes had a rather narrow view of fashion as most of their clothes, while different in texture and color were basically the same and even the same long and tall hats. Oh well, at least she got to give them a few tidbits though for some reason when she mentioned one of her ideas was inspired by the coat Dib wore the Gnomes were very tensed and politely rejected her offer, strange she had to ask Dib what he did that deserved such reaction.

Meow

She stopped when hearing the unmistakable sound of a cat, she in curiosity tracked the sounds and looked around until she found a bush, she slowly put the bush's branches away to get a better look and she found what it was.

It was a cat, though not a normal cat as it was blue sky and had more than just four limbs, it was licking a paw before it noticed her attention and looked and saw Mabel looking at her.

"Awww, where did you come, little buddy?" She cooed and predictably she found the abnormal cat cute, unable to resist the adorableness she slowly reached her hand and to her delight the strange cat wasn't apprehensive and when she reached she managed to reach and caress its head and the blue cat in response cooed. She continued caressing it until she managed to convince it to hang on her hands.

"Hungry little guy? I know a place to get warm milk. Oh, my brother and Dib are gonna like you!" She gushed at it and then walked toward the Shack.

Outdoor of the Shack….

Mabel came with her new creature which she carried and there she saw Zim and Dib in another argument.

"Hey guys! Look what I have found!" She called them.

The Membrane boy looked back "We are busy- AH!" he yelped in shock and terror at what he saw.

When Zim and Dib turned they both froze with Dib noticeably becoming pale. Zim's eyes widened so much that his eyes could pop out of his skull any moment and both stared in terror at the blue cat that looked as if they just saw a ghost.

Meow

"AAAAAAAAAH!" Both of them shrieked at the same time with Dib reeled back while Zim rather shakenly brought two blasters from his Pak and pointed at the innocent-looking weird cat.

"Woah woah what's the scare here!?" Mabel, taken aback by their visceral reaction, asked.

"SNARL BEAST! SNARL BEAST! SNARL BEAST!" The Membrane Boy stammered loudly and pointed a shaken finger at it as if the cat was the Devil itself.

"What on Sal even is a snarl beast?"

"One dominant species of the most dangerous Death World known in the known universe!" Zim elaborated with a tone devoid of his usual sneer or haughtiness showing how much of a threat Zim considered the Snarl Beast being.

That was when Gaz showed up from the door to see what the shrieks were about and was not impressed on what was about "Really? Ailurophobia now?"

Just then, an alien blue cat glanced at Dib and Zim and it jumped off Mable and while doing so suddenly morphed and changed into a larger form.

"WHAT THE HEY HEY!?" Mabel exclaimed at the sudden transformation and saw why the creature was named 'The Snarl Beast.'

Other than growing bigger its mouth became leechlike with a series of jagged teeth and more leech mouths with extra heads came out and its claws got sharper.

SNARLED!

It snarled loudly living up to its nickname.

"Okay…Now I see why you were scared crapless by it." Gaz in awe of the alien monstrosity that used to be the blue cat commented.

It then lunged at the Membrane Boy and the Invader both shrieked high-pitched with Zim running and Dib getting snatched away by his sister both running in the opposite direction while the sheer weight of its attack broke the wooden door. It for a brief moment was trying to choose between Zim and Dib only to then move toward Zim who while running was shooting his blasters at him and yet the creature having agility surpassing a tiger dodged his blasts.

"NO, no wait! Bad kitty bad kitty!" The Pines girl tried telling Snarl Beast to stop attacking but it paid her no mind.

Suddenly, a blast of blue plasma hit the beast making it growl coming from Dipper who with Wendy was running toward the Shack. The alien beast launched toward Wendy who thanks to her Lumberjack training managed to duck away from being smashed and while doing so hit her ax at the monster's right leg.

GROWL

It growled in pain so it retaliated by hitting Wendy with her other paw sending her flying and hitting Mabel both falling on their backs Dipper had to get down from being hit away but his Magnet Gun was hit away.

Snarl Beast returned its gaze with its many maws toward Zim.

"No! Take him!" Zim grabbed Dib and used him as a human shield "ACCEPT THE BIG HEADED CHILD AS TRIBUTE SNARLING GOD!"

"MY HEAD IS NOT BIIIIIIIIIIIIG!" Dib shrieked out, the Snarl Beast by its maws held Zim and Dib carefully and then ran away as they both shrieked their lungs out.

"Your life's on the line and you complain about the size of your head!?" Wendy incredulously hissed as he held a hand on her head and helped Mabel to get up.

"That's the idiots for you." Gaz blankly commented as the said idiots were taken away.

The Beast ran over and over in the depths of the wood until it finally stopped and dropped its two hostages away.

"Too many teeth…" Dib in a fetal position and his phobia of teeth kickstarter mumbled. Not that Zim would blame or sneer at him as he too was shaken and he was pretty sure if Snarl Beast were to hold them wrongly or give a little push the maws would break them like sticks.

Just then, a mysterious voice came with a haughty yet familiar voice. "Well, Well…seems one of my minions got what I wanted for delivery."

Zim looked and what he saw made him get up in outrage "YOU!" he pointed accusingly at the person he knew.

The Irken with baleful purple eyes smirked who was none other than Tak "In the Flesh." while her own SIR unit slithered on her shoulder.
