One day in Unikingdom, Unikitty was testing out a new stunt, "And now, ladies and gentleman, I bring you..." she announced as she was standing in the castle's throne room before taking out two bars of soap, "Two ordinary bars of soap! But, when tossed by a skilled professional, they become..." She then tossed the bars of soap across the floor, followed by Puppycorn landing on them from out of nowhere.
"A one-way ticket to pain!" he said as he slid across the floor before sliding up a ramp and crash landing on the floor.
Right below, Dr. Fox was in her lab, trying to make a house of cards. The crash made the cards fall over when she was about to put on the last one, "What the?" she said when this happened.
Back up top, Unikitty and Puppycorn were sliding across the floor, with Unikitty riding on top of Puppycorn, "Heave, ho!" she shouted, right before she and Puppycorn crashed into a wall.
At this moment, Dr. Fox came up from the lab, "What are you guys doing!? Time is a precious resource you know, just as important as water. It's like your wasting water until the ocean is nothing but a dried up husk of its former self. You don't want that do you?" she asked.
"Me and Puppycorn were just performing a sacred happiness ritual to help out the citizens, and the only way the ritual works is for us to get hurt... real bad." Unikitty explained.
"Who's the moron that told you that?" Dr. Fox asked. Right behind her, Master Frown was looking through a window. He got a nervous look on his face before running away, "Look, instead of hurting yourselves, I have something real important that you can do for me." Dr. Fox said.
Later, the three of them were standing in front of a door in Dr. Fox's lab, "So, are you guys ready for your super..." Dr. Fox said.
"Super!" Unikitty and Puppycorn repeated excitedly.
"Special..."
"Special!"
"Secret..."
"Secret..."
"Assignment?" Dr. Fox finished. This resulted in both siblings staring at her silence for a moment before freaking out in a anticipation, "You two are going to paint the inside of my study!" she said while opening the door to the study. The siblings cheered, but Dr. Fox stopped them, "But, let me give you two a warning." she said in a serious tone before handing them two paint buckets, "This paint, is absolutely permanent. It will never come off. So if I see even one drop on anything but the wall, I'll take off your tails and mount them on the fireplace!" she said while holding up two trophy mounts with the sibling's names on them. They backed up nervously into the study before Dr. Fox smiled and said, "So, have fun with the job!" before slamming the door shut.
The siblings turned around and got a good look at the study. It was an eloquently decorated room with fancy-looking furniture. There walls were cluttered with various objects, paintings, and pictures, "Gee, Dr. Fox sure has a lot of precious items to drip paint on." Unikitty said, "You think we should take this stuff off the wall?"
"No way sis, we're not getting paid to move stuff." Puppycorn said.
"We're not getting paid at all." Unikitty pointed out.
"Well that's what I'm saying, we're not getting paid and that's final." Puppycorn said.
"OK, we'll just have to paint around all this stuff then." Unikitty said.
"Good, just don't pay me." Puppycorn said.
"First we gotta set up the tarp." Unikitty said while holding up a sheet.
"Tarp away!" Puppycorn said while holding up another part of it.
They threw the sheet down so it covered the floor, in reality, it only covered about a small portion of it, "We're gonna need more coverage little bro." Unikitty said, leading to them putting more small sheets all over the floor, not really covering all of it, "Now that's what I'm talking about. OK, I think its time for us to open these cans of permanent paint now." she said nervously.
"That will never, ever come off." Puppycorn said.
"And we get paint on anything, Dr. Fox will take away our tails..." Unikitty said.
"And mount them on the wall." Puppycorn said. Unikitty then took out a screwdriver and started to pry the lid of the paint can open, "Careful Unikitty, careful Unikitty, careful Unikitty, careful Unikitty, careful Unikitty, CAREFUL UNIKITTY!" Puppycorn shouted repeatedly as she did so.
"Puppycorn, the lid's already off." Unikitty said with the now open can beside her.
"Oh, now its my turn!" Puppycorn said before slamming an axe down onto his paint can, but not opening it.
"Uh, I think you better let me handle this one little bro." Unikitty said while taking the can away. She then tried opening it with the screwdriver, successfully getting it open. However, a drop of paint flew out, causing both siblings to scream. The drop bounced off the sheets, making them scream some more before it dropped back into the can. The both breathed a sigh of relief, "Well, glad that's over with." Unikitty said before walking over to her can and getting out a large paintbrush, "Alright little bro, let's get our brushes started!" She then looked at the brush nervously, "Uh, maybe we should start with a smaller brush." she said before putting the large brush away and getting out a small brush handle. She inserted the tip into her nose and pulled out a single hair. Puppycorn did the same, but pulled out a large chunk of his nose hair. Unikitty then carefully dipped her brush into her can and walked over to a section of the wall, "Well, here we go. Gonna get started with painting this wall. With the permanent paint that we're not supposed to get on anything, but the wall. Well, here it goes." Unikitty said.
ONE HOUR LATER
"Just a few more minutes of mental preparation and I'll be painting this wall." Unikitty said while sweating lightly.
TWO HOURS LATER
"I'm getting to the painting." Unikitty said, now sweating even more, a few puddles appeared around her.
THREE HOURS LATER
"Could you move it along? I'm running out of time cards." Puppycorn said while taking the card down.
Unikitty was now sweating heavily, a pool of her sweat surrounding her, "OK, here it goes." she said before painting a single line between two mounted objects. She smiled when she saw that nothing happened. The paint then started to drip down the wall, causing Unikitty to panic and blow the paint away from any objects in its path as it dripped down the wall. She then got out a dryer and used it on the paint, causing it to stop dripping. She blew on the dryer as if it was a smoking gun, "Yeah..." she said with sly confidence. She then noticed that she had accidently created a giant, floating paint bubble, "Oh no! What could be worse than a giant paint bubble!?" she yelled.
"I know!" Puppycorn said before dipping a bubble want into his paint bucket and blowing out another paint bubble, "Two giant paint bubbles!" he said, causing Unikitty to scream in fear.
The bubbles then merged together to form a bigger bubble, "Puppycorn?" Unikitty asked.
"Yeah?"
"I don't think this bubble can get any bigger."
"Nonsense!" Puppycorn said, now having an air pump attached to the bubble. He started to pump air into the bubble, making it bigger.
"Little bro, no!" Unikitty shouted before the bubble exploded. However, instead of getting over everything, the paint splattered onto the unpainted parts of the wall. Unikitty left her 'in cover' position and moved out of the way, the paint getting an outline of her filled in. Like that, the room was completely painted, "We did it! We painted the whole study. And all without getting a single drop of paint on anything but the- FLIPPING FLAPJACKS WHAT'S THAT?!" Unikitty screamed as she noticed a diploma on the wall. Upon microscopic inspection, there was a single tiny drop of paint on it. Unikitty's eyes then broke like glass, letting her iris' leak out, followed by her falling onto the floor, "Puppycorn, do you know what that is?" Unikitty said, her eyes going back to normal.
"Hmm... It's a piece of paper! I win!" Puppycorn said.
"That's just a piece of paper! That's Dr. Fox's high school diploma! Her most cherished possession! And we got paint on it!" Unikitty said in panic.
"I think you're overreacting sis, I don't see any paint." Puppycorn said.
Unikitty then took the diploma off the wall, "OK, no problem. Just need to wipe it off." Unikitty said before taking off her tail and using it to wipe off the paint, "There, I think I got it." The paint was now visible, a straight white line across the diploma. She then started to panic as she tried wiping again, only to have the paint now cover the rest of the diploma. This left it looking like a blank piece of paper, causing Unikitty to scream.
"Oh, now I see it." Puppycorn said.
"This is not good little bro, this is not good! Dr. Fox is gonna come back soon, and when she sees what we did to her high school diploma..." Unikitty said as she and Puppycorn imagined Dr. Fox drinking tea by the fireplace, with both their tails stuck to the wall mounts from earlier.
This image caused them to scream while holding their tails, "What are we gonna do!?" Puppycorn asked.
"OK, we just need to use whatever methods we can think of to get this paint off." Unikitty said. The first thing she tried was using a sanding tool to get the paint off while Puppycorn held it, "Did it work?" she asked.
"Nope." Puppycorn said, the diploma remained the same, but his paws were now completely gone.
The next thing was using a high-powered hose, with Puppycorn screaming as he was shot with the water, "Did it work?" Unikitty asked.
"Nope." Puppycorn said, the hose burned right through him, except for where he held the diploma.
One more thing they tried was Unikitty trying to knock the paint off with a bat, resulting in Puppycorn getting injured repeatedly, "Nothing working!" Unikitty shouted.
"Wait sis! We're not cavemen!" Puppycorn said before bringing the diploma to a computer, "We have technology." he said before slamming the computer down on the diploma in a rapid fashion, which did nothing.
"It didn't work." Unikitty pointed out.
"This is all Dr. Fox's fault! If she didn't have that stupid diploma in the first place, then none of this wouldn't have have happened! I mean you could just hang up some random diploma and put it on the wall, then you wouldn't even tell the difference! You might as well just grab a random piece of paper, edit it to look like a diploma, and put it on the wall. Which is-" Puppycorn ranted before Unikitty interrupted him.
"Good idea Puppycorn, find a piece of paper!" Unikitty said.
"I don't see where you're going with this, hey paper!" Puppycorn said, finding a piece of paper after looking for a while.
"Our tails are saved little bro! Now let's-" Unikitty started to say before Puppycorn put the paper in a shredder, causing Unikitty to complain in disappointment. The paper was rejected and came back out, causing Unikitty to urge Puppycorn to take it out, only for him to push it back in. This happened one more time before the paper finally went in for good.
Puppycorn was then rolling around in the shredded paper, "Try this sis, it's fun!" he said.
"OK, no point in worrying now." Unikitty said while walking up to a mirror, "Don't panic princess, panic is the enemy! You are strong, find your strength and you will overcome-" she started to say before hearing Dr. Fox singing a song while coming closer.
"You're on your own friend." Unikitty's reflection said before walking off.
Unikitty panicked and ran around the room for a while before coming up with a plan, "Quick Puppycorn, put Dr. Fox's diploma back on the wall! I've got an idea!"
Dr. Fox continued singing while she opened the door to her study while carrying a shopping bag with her, only to find the lights turned off, "What the?" she said.
Unikitty and Puppycorn stood in front of her in the dark, with only their eyes showing, "We're all done Doc, everything fine." Unikitty said.
"Yeah, and you don't need to look around. We already did that for you." Puppycorn said.
Dr. Fox turned on the light to find that they were both giving forced, nervous smiles, "You two are acting like you got a dirty little secret." Dr. Fox said, causing the siblings to lose their smiles, "Ha! Just kidding. Now, let's see how you did." Dr. Fox said before starting to look around, "Not bad guys, not bad. I see a smooth texture, high gloss, no bubbles."
"OK Doc, glad to help you out. We should get going now." Unikitty said before she and Puppycorn started to walk out of the room.
"Great Scott! Look what you did!" Dr. Fox suddenly shouted, causing the siblings to get down on their knees and apologize profusely, "Sorry? You dusted all my knick-knacks. That was real nice." Dr. Fox said before noticing something else, "Pythagoras' Theorem! What's this!?" she shouted while Unikitty and Puppycorn gave their apologies once more, "Oh, and I assume the floorboards painted themselves. That's what I call craftsmanship." Dr. Fox said as she observed a small mural at the bottom of the wall depicting rockets flying through space. She then noticed something else, "Sweet mother of Einstein! You messed up my dip... display!" she shouted while pointing towards a display rack with various dipping sauces. Unikitty and Puppycorn just stared at her, "All the dips in this dip display were in alphabetical order!" Dr. Fox said before moving two of the dips into their correct positions, "And you thought I wouldn't notice. Well, thank you guys for your help. Alright, you're free to go- ow!" Dr. Fox said while walking away, a stack of pictures stopping her in her tracks. She stepped back and rubbed her head, "Well, that's strange. I don't remember having a stack of paintings where my high school diploma used to be. In fact, I don't remember having this picture at all." she said, moving the photos out of the way as she didn't recognize them. Unikitty and Puppycorn looked on nervously as she got closer to the diploma. "Or this one, or this one, or this, or this-" Dr. Fox said while removing photos, eventually coming to Unikitty's head in front of the diploma.
"Hey Dr. Fox." she said awkwardly.
"Unikitty, what are you doing?" Dr. Fox asked.
"Oh, you know, just hanging around." Unikitty said.
"Boo!" Puppycorn said.
"Can you please reattach your head?" Dr. Fox asked. Unikitty obliged and did so, but still having her head in front of the diploma, "OK, now you're just being silly." Dr. Fox said as she removed Unikitty, allowing her to see the diploma.
"No, no, no, Dr. Fox, no! Don't look at the trick!" Unikitty said.
Dr. Fox then turned towards the siblings with an angry look, "Did you two get paint all over my high school diploma!?"
"We're sorry Dr. Fox." the siblings said in unison.
Dr. Fox then turned back to the diploma, then back to them, "And did you draw on it with crayon?" she said, pointing out that the diploma now sported a poorly drawn smiley face along with the words 'Dr. Fox is smart.'
Unikitty turned towards Puppycorn, who shrugged while holding up a crayon, "Well, I thought, you know, maybe she'd buy it." he said.
"Alright guys, you know what I'm gonna do now!?" Dr. Fox said.
"You mean our tails?" Unikitty asked.
"Can I chase mine one last time?" Puppycorn asked.
Dr. Fox then took her diploma off the wall and licked it, causing the paint to melt completely off. She then stuck it back on the wall, "There we are, good as new." Unikitty and Puppycorn stammered in shock for a while before Dr. Fox sidled up next to them, "Yeah, I lied, this paint actually comes off with saliva." she said.
Unikitty's face lit up in realization, "Oh, I get it Doc! You told us that the paint was permanent so that me and Puppycorn would be more careful and not get paint on anything." she said.
"Nah, I just like to mess with you!" Dr. Fox said before laughing. Unikitty and Puppycorn didn't find it amusing and left the room in annoyance. Dr. Fox continued to laugh, not realizing that she getting her spit all over the wall, causing the paint to melt. She stopped laughing when she realized what happened, "Ah crud, I really need to learn how to say it, not spray it."
