((Yes, I just noticed that American cartoons can be just as awesome as anime.))
This is the story of a 13-year-old boy and his shape-shifting dog. One day, Finn the Human decided to head back to that not-a-cat kingdom. Sure, that place was not actually a kingdom of cats, but it was one of Finn's favorite place to visit when he's feeling down. And, not callings spoilers, Finn had a good reason to feel down.
"Hey, don't feel bad, Finn. He's just not worth it." Jake bent down to pet a cat, but the cat hissed at him and run away. "What?"
"But he..." Finn sighed. "It's just that, even after I helped him, he still..."
"Don't worry, I know what will cheer you up. A FLAMING METEOR HEADING OUR WAY!"
Finn stared at him. "That sounds awesome."
"No, A flaming meteor headed our way!" Jake grabbed Finn and pointed him to the sky. Indeed, a flaming meteor was indeed heading their way. Jake sprang away with Finn as the meteor struck the ground. It left a very small crater, though, and when the smoke cleared, Finn, Jake and the cats could see that the meteor was actually a giant ball of yarn. Of course, it wasn't a giant ball of yarn as it unraveled and became a white suit that Finn thought looked like a white version of what the businessmen wore.
The clothing drew closer to Finn, and the boy had a feeling he did not want to wear that suit. Indeed, for that suit was an alien life-form known as a COVERS, and it had a goal of converting all humans into-
"Hey, snazzy pants. Finn's the last human here." The COVERS turned its neck collar towards Jake. "Yeah, don't mention his parents to the little guy."
The COVERS waved around. Jake shrugged. "Yeah, sorry, but everything changed after the last thousand years. I just noticed, but most of BP's candy subjects don't wear clothes."
The COVERS flopped to the ground. Finn blinked. "Oookay. What was that about?"
"Oh, just some clothes that wanted to destroy the world. He said that their first group took a million years to populate the world with humans, and he can't use the world as a rocket ship since there's only you and that one girl." Jake had to stifle a laugh. "That's crazy. Billions of humans."
"Uh, don't worry, Mr. Clothes. Maybe you could do something other than destroying the world? Hey, let's see what PB has to say."
Princess Bubblegum unlocked the door to her secret underground lab. Here, she was born out of primordial pink ooze. However, if Finn and his friends had looked any further, they would have seen another door, which hid another secret of her upbringing. If not for that secret, she would have the same intelligence as her subjects, though she would be too dumb to create them in the first place.
For the Candy Kingdom was born on top of a grave. The name on the grave was worn off, but when the kingdom was born, there was nothing but dry bones and red threads. Princess Bubblegum had already reburied the skeleton, but she had woven the threads into a sheet. Every now and then, she came back to this room, feeling the embrace of ever-growing knowledge. There was a reason why only Peppermint Butler wore clothes, and that reason was because Lemongrab. And some of the other kingdoms. In short, she did not trust anyone to be smarter than her, but she dared not make an intelligence-dampening ray that could backfire on her.
Princess Bubblegum looked into the drawer where she kept the sheet. However, it seems that instead of the sheet of red fibers, there was a little girl hudded in there, a bit of red in her black hair and a small red dress around her. Bubblegum frowned. "Well, I should have known the catalyst for my evolution would have evolved as well. I better cut out the unwanted parts."
Princess Bubblegum pulled out the top drawer and grabbed a pair of scissors. However, she heard a bell. She installed that for the very purpose of making sure to be back at the kingdom before anyone explores the dungeon for, I don't know. "Oh, what now, Finn?"
Bubblegum closed both of the drawers and left the room, locking it behind her. If she had not been in a rush, she would have noticed that the small girl was gone from her drawer already.
