One day in Unikingdom, Unikitty was looking for Dr. Fox, "Dr. Fox? Dr. Fox? Are you here?" she called out. She looked all throughout the castle, the study, the kitchen, the throne room, and even the attic. Her search eventually took her to the balcony where she scanned the view for her friend, "Come on Doc, where are you?" she wondered. Suddenly, there was a rumbling sound as a panel hidden in the castle grounds opened up, followed by a rocket ship rising out of it, "Whoa." Unikitty said, staring at the rocket in amazement.
From the rocket's window, Dr. Fox poked out, waving at Unikitty, "Hey Unikitty, how do you like my new rocket?" she asked.
"It looks great Doc!" Unikitty said.
"Come on in, I'll show you around." Dr. Fox said before going back into the rocket, with Unikitty following her through the window. The both of them were in one of the rocket's rooms, one filled with science equipment. Dr. Fox was busy writing on a clipboard.
"Woah, what are you gonna do with it?" Unikitty asked.
"I'm going to the moon Unikitty." Dr. Fox said while pointing at a picture of the moon hanging on the wall.
"The moon! Can I come?" Unikitty asked.
"Sorry Unikitty, but I'm conducting an important experiment up there and I can't risk taking along any unnecessary cargo or passengers." Dr. Fox explained.
"But I don't take up that much space!" Unikitty said before jumping into a beaker, "I can fit in this." She then ducked into the beaker, forming with its round shape. She then jumped into two more beakers, changing shape with them before being sucked into a tube attached to the last one, "And this, and this."
"Unikitty, can you quit fooling around please? Look, see this?" Dr. Fox said while pointing at her clipboard, which had many different math equations written on it, "This is science. I don't have time for fun and games, and I definitely don't have time for stowaways."
"Fine." Unikitty said before speaking in a deep voice while shutting herself inside a caged metal cube. "Put me in the cell, I don't mind!"
"That's the air vent Unikitty." Dr. Fox said before pressing a button on the wall, causing Unikitty to be shot out of the vent, "I need that too."
"Please, let me go, please?" Unikitty said while looking at Dr. Fox with sad eyes.
Dr. Fox sighed before saying, "Fine, you can ride with me in the cockpit if you promise to-" she started to say before Unikitty flew up excitedly.
"Yay! Going to the moon! Moon ride! Moon ride! Moon ride!" she chanted while flying around the room while Dr. Fox just stood there with an annoyed expression.
She eventually produced a grappling hook from her coat and shot it at Unikitty when she was coming around, causing her to be pulled towards her, "Just please don't touch anything."
Now outside the rocket, Dr. Fox was operating a pump-gun. Unikitty watched while she did so, "Wow, get a load of that pump gun. Are we gonna go fight aliens on the moon?" Unikitty asked while making punching motions with her paws.
"Ah, hush silly." Dr. Fox said as she finished pumping. She then fired the gun at three bottles set up a few feet away, resulting in them being encased in nets, "This is just for harvesting moon rocks."
"Well, when you're done playing with rocks, you could use that for some serious alien hunting." Unikitty said.
"Aliens? Are you crazy? I've done a lot of research on the moon and their are no aliens." Dr. Fox said.
"Oh, Dr. Fox. How could you be so naïve? There's elements all around us. Have you ever considered... Atlantis? Bigfoot? 99 cent stores? Or what about those mysterious circles that pop up in corn fields overnight?" Unikitty said while drawing a circle in the ground that surrounded both her and Dr. Fox before pointing at it in surprise, "Ah! There's one now!"
"Look, Unikitty, I'm telling you that there is no such thing. Now go to bed and get some shut eye. Meet me by the rocket tomorrow at dawn, and leave your silly alien notions behind." Dr. Fox said.
That night, Unikitty was asleep in her bed. She was snoring, but occasionally opened her eyes to look at the alarm clock beside her bed. "Oh, hurry up!" she said while shaking her clock before putting it back. She then took out a roll of packing tape, "This oughta do the trick." she said before applying a strip of tape to both her eyelids to keep them shut, going back to sleep afterwards.
"Hey sis!" a voice sounded, causing Unikitty to open her eyes and rip the tape off her eyelids in the process. The voice turned out to be Puppycorn standing in her window.
"Puppycorn, can't you see I'm sleeping here?" Unikitty said.
"Well, I heard you were going on that moon trip tomorrow, so I thought I'd give you something." Puppycorn said.
"A present?" Unikitty asked.
"No. Unikitty? Is Dr. Fox's rocket alien proof?" Puppycorn asked.
"There are no aliens Puppycorn, just ask Dr. Fox." Unikitty said while rolling over.
"I guess in that case you won't be needing this alien repellent for your trip." Puppycorn said, pulling out what looked like an aerosol spray can.
Unikitty turned back around, "Alien repellent? Let me see that." she said while taking the can from Puppycorn and reading it, "New Alien Outdoor Window Protection. Warning: Does not stop burglars. Oh you're right little bro, we better go spray those windows."
Both siblings stood outside the rocket, "Look how big it is sis!" Puppycorn said.
"It's pretty impressive alright." Unikitty said.
"Come on, let's go." Puppycorn said while heading up to the rocket's loading dock.
"We're just here to spray the windows Puppycorn." Unikitty said while flying after him. They both reached the door of the rocket, a lever standing by it.
"Huh, I wonder how we get inside." Puppycorn thought while looking at the lever.
"We don't, we're just spraying the-" Puppycorn pulled the lever, causing the door to open right on top of Unikitty, "-windows." she finished.
"I opened it Unikitty! Come on!" Puppycorn cheered while pulling Unikitty inside. Once inside, they found themselves in a room filled with many gadgets and consoles, "Isn't this just the coolest thing you've ever seen?" Puppycorn said.
"Yeah, just don't touch any-" Unikitty started to say before Puppycorn rushed to a console with a joystick in front of a screen and started playing with it.
"Look, I'm winning!" he said.
"Puppycorn, cut that out." Unikitty said while trying to get his attention, "Puppycorn, this isn't some kind of game. This is Dr. Fox's big rocket, not some kind of fun... house?" she said while turning towards a reflective surface that distorted her image.
"Woohoo! Winner! Yeah, high score!" Puppycorn cheered.
"Say little bro, what game was that anyway?" Unikitty asked while sitting next to him.
"I'm not sure. Hey, what's this do?" Puppycorn asked while pulling on a lever attached to the seat.
"Puppycorn, I don't think you should-" Unikitty started to say before she and Puppycorn were launched into the air through a hatch on the nose of the rocket.
"I like rockets." Puppycorn said before they fell down back onto the seat they were sitting on, "More, more!" he said while going to console with buttons on it.
"No more." Unikitty said before Puppycorn pressed a button, causing the rocket to vibrate for a few seconds, "OK, one more." Puppycorn pressed the button again, causing the same effect to happen, "OK, that's enough let's go." Unikitty said before Puppycorn pulled her back.
"Wait, I think this one starts it." Puppycorn said, moving his paw towards another button before Unikitty stops him.
"Puppycorn, I'm the space traveler here. So, I happen to know that that particular button is right over here." she said while pressing the biggest button on the console. This causing alarms to blare out as the rocket starts up.
"It's starting the rocket!" Puppycorn shouts.
Upon hearing the alarms, Dr. Fox wakes up from her bed with an annoyed look on her face, "Ugh, Unikitty..."
The rocket then takes off, with Unikitty and Puppycorn being flung back towards the base of the rocket at high speed, "Hang on sis!" Puppycorn says as the base grows closer and closer. Fortunately, the rocket exits the planet's atmosphere, bringing the sibling's fall to a halt and causing them to float, "Hey, we stopped falling!" Puppycorn said.
"Look, we're in space now! Whee!" Unikitty said while pointing out a window and flipping though the air.
Meanwhile, Puppycorn begins to flail around, "Uh, somebody get me down... or something!" he said, causing Unikitty to laugh.
The rocket then reaches the moon, spinning around it while it looks on with a confused expression, "Hey sis, watch this!" Puppycorn said before shooting some toothpaste from a tube into a glob of peanut butter, causing it to get stuck.
"Hey, you got your toothpaste in my peanut butter!" Unikitty said, causing both of them to laugh. The rocket took one more lap around the moon before heading back down to Earth, "Hey Puppycorn, I can do this!" Unikitty said before effortlessly lifting a huge barbell on one paw, walking around with it afterward. The rocket then reentered the planet's atmosphere, causing the gravity to go back to normal, resulting in the barbell to crush Unikitty's paw into the floor.
"Hey, who turned the heavy back on?" Puppycorn asked.
"We must be landing!" Unikitty said.
"Alright!" Puppycorn said while running to the exit, with Unikitty following him. Her paw stretched a bit before being freed from under the barbell.
Meanwhile, Dr. Fox was flying upward with a jetpack while wearing a spacesuit, "Unikitty, you're my friend and I appreciate you. But honestly, you drive me crazy sometimes." she monologued to herself before exiting the planet's atmosphere and landing on top of the moon.
Back on the planet's surface, the rocket landed in Frown Town, right in front of Master Frown's apartment building. Unikitty and Puppycorn popped out of the rocket wearing spacesuits, "Wow, it sure looks a lot like home." Puppycorn said before noticing Pet Pet in front of the building, "Hey, there's Pet Pet! Come here Pet Pet." he started to say.
"Wait! Don't go near it little bro. Don't you see? The aliens are projecting our memories onto the environment! They're trying to confuse us, Puppycorn." Unikitty said, a pump-gun now in her paws.
"So you mean to say they've taken what we thought we think and make us think we thought our thoughts we've been thinking our thoughts we think we thought? I think..." Puppycorn asked.
"Yeah. But I'm not going to fall for it!" Unikitty said while giving the gun a few pumps and firing it at Pet Pet, encasing him in a net.
"Pet Pet"
"Yeah!" Unikitty cheered.
"You got 'em sis! Won't Dr. Fox be proud?" Puppycorn asked.
"Dr. Fox! I forgot all about her. She's gonna hate us for stealing her rocket. But won't she feel silly when I bring her back a real live alien? Oh, she'll love us!" Unikitty said before grabbing Pet Pet, "Come on little bro, the more the merrier!" She tossed Pet Pet into the rocket's storage hold, causing the 'Subjects' counter to increase by one.
"Alien hunting! Alien hunting!" Puppycorn chanted.
"Shh! Don't let them know we're onto them. Uh, yeah! 'Alien Hunting,' I saw that on TV too. Gee, Puppycorn, why don't we check in on our old pal Master Frown and see what he's up to. Make sure your gun is pumped." Unikitty said before sneaking into Master Frown's apartment. Puppycorn pumped his gun a few times before following her inside. They found Master Frown was sleeping on the couch in the living room, mumbling as he did so, "Look at it little bro, it's disgusting." Unikitty whispered before Master Frown suddenly lifted his arms up and waved them around, causing both her and Puppycorn to aim their guns at him in caution. The Doom Lord put his arms down and seemed to fall back asleep.
The two siblings snuck closer to him, "It's even uglier up close. Let's begin the analysis." Unikitty said, prompting Puppycorn to take out a small device while she took Master Frown's covers off.
"Wait, what's that?" Puppycorn asked, pointing at a wet, red bag underneath Master Frown. Unikitty carefully slid it out and held it in front of Puppycorn, "Ugh, I think I'm gonna be sick." he said in disgust.
"Puppycorn, do you know what this is?" Unikitty asked.
"Stinky?" Puppycorn answered.
"No, it's an egg sac. Let's look at the embryo." Unikitty said while putting both her paws under it to hold it.
Puppycorn takes out a flashlight and turns it on, holding underneath the bag, resulting in silhouettes of Unikitty's paws being shown, "Twins." they both said.
Suddenly Master Frown turned over in his sleep, inadvertently putting on of his arms on Puppycorn's helmet, "Uh, pardon my French but GET THIS THING OFF ME!" he shouted before Unikitty got tangled in Master Frown's other arm. They both started screaming while waving the arms around, causing Master Frown to wake up and notice them.
"Unikitty!? Puppycorn!? What are you doing in here!? And give me back my arms!" he said while pulling back his arms.
"Its awake!" Puppycorn shouted in alarm.
Unikitty took out her pump gun, "Let's blast the little phony!"
"No wait! Get away from me!" Master Frown shouted before jumping off the couch right before a net from from gun encased it.
Unikitty jumped onto the couch and screamed, "OOGIE, OOGIE, OOGIE, OOGIE, OOGIE!" before jumping off and chasing Master Frown. Puppycorn gave a battle cry of his own before following his sister's lead. The sound of the pump-guns shooting could be heard from the outside of the apartment, right when Brock was coming home. He encountered Unikitty and Puppycorn carrying Master Frown outside, who was now trapped in a net.
"Oh, hey guys. A little late out for a larping session, huh?" Brock said with a chuckle before Unikitty and Puppycorn aimed their pump-guns at him, causing him to hold his hands in the air, "Wait! Don't shoot! ...OK, shoot me, but please don't take my video games!" he begged them.
"We don't want your games... Moon Man!" Unikitty said before she and Puppycorn fired their guns at him, trapping him in a net. Both siblings threw their catch inside the rocket's storage hold afterwards.
"Look at 'em squirming around in there." Unikitty said.
"Ew, gross." Puppycorn said.
"Well, more where that came from." Unikitty said before closing the storage door.
Both siblings headed towards Bim Bom's house next, where she was writing at her desk, "Unikitty, what are you doing here so late?" she asked before being shot with the pump-gun, "Well, whatever it is, it's certainly affecting my opinion of you." They then capture Eaglelater as he was opening his medicine cabinet, FeeBee as she was doing nightly maintenance on her flowers, Hawkodile as he was training, before moving on to everyone in Unikingdom and Frown Town.
After their capturing spree, Puppycorn is trying to shove everyone they captured into the rocket, "Uh, sis I think we might have to take a second trip." he said.
"There's no time for that, just push harder." Unikitty said.
At that moment, Dr. Fox landed right by them on her jet pack, "Unikitty, what are you doing? I turn my back on you for two seconds and you go and make a huge mess! I mean look at you, bagging up all of our friends and neighbors as if they were half-off groceries! Both of you turned my little science experiment into a disaster! You oughta be ashamed of yourse-" she started say before being captured by the the siblings.
"Nice try, Dr. Fox." Unikitty said as she and Puppycorn carried her to the rocket.
"Or should I say, Miss Alien Pants?" Puppycorn said with a laugh.
"Aliens!? Is that what this is about?" Dr. Fox asked before she was thrown into the rocket, "Guys, this isn't the moon! We're still on Eart-" the door was closed before she could finish.
"It's just like they say, you can't trust anyone." Unikitty said before she and Puppycorn gave each other suspicisious looks before grabbing their pump-guns, "So, you were an alien all this time, and you didn't even tell me." Unikitty said.
"I didn't even know." Puppycorn said.
"Oh yeah? Well I got you now." Unikitty said.
"Oh, but it's not you that's got me." Puppycorn said while moving forward, causing Unikitty to drop her gun and cower in fear with her eyes closed, "It's-" the sound of the pump-gun going off sounded and Unikitty opened her eyes to see that Puppycorn shot himself, "me that's got me."
Unikitty then started up the rocket, "Boy, I can't wait to see the look on Dr. Fox's face." she said as the rocket entered space, traveling halfway around the moon before the engines sputtered out, making the rocket crash on top of it, "Dr. Fox, I'm back!" Unikitty called out before looking outside, "Wow, Unikingdom sure looks different." She saw the moon's surface in front of her and saw Earth in the distance, which made her come to a realization, "Uh-oh." she simply said.
"Unikitty! The aliens would like a word with you!" the captured citizens shouted from inside the ship.
