Hello everyone! I've been meaning to write this for a while now. I love Gravity Falls and Invader Zim, and I realized that the episode "Little Dipper" would be perfect for Invader Zim. So I bring you the parody of this great episode! "Little Zim!"

Disclaimer: I don't own Invader Zim or Gravity Falls.

"Alright children, you may now begin." the happy, overly cheerful Mr. Elliot chimed. As Ms. Bitters wasn't there this morning (for reasons still unknown) Gaz's teacher had to be the class's substitute. And he thought that he would set up a fun activity for the children to begin the day with. Chess. He chose chess.

Everyone had set up their games, and had partnered up with someone to play it with. Leaving only Dib and Zim with out opponents. Which automatically made them partners.

"Remember to play fairly." Mr. Elliot reminded.

"Um... Little thing to black space nine." Zim said, moving one of the pieces.

"It's a pawn, that's not your color, and stop destroying the tiny horses!" Dib responded, snatching one of the knights Zim was about to crush from his gloved hand.

"I don't like them! They must be annihilated!" he cried out, shaking his fist dramatically. Dib rolled his eyes before knocking over his king.

"And... Checkmate!"

"Oh come on, you cheated!" Zim yelled, pointing across the table.

"No I didn't! I one fair and square!" Dib took out a notepad and put another tally mark under his name.

"Hey, could one of you pass me that bottle of glue?" Keef asked, coming seemingly out of nowhere. He pointed up at the top shelf of the classroom bookcase, where a bottle of glue sat innocently.

"Fine" Zim responded, standing up.

"Actually..." Keef said, trailing off. "Dib's taller."

"What? No he isn't! We're the exact same height! We've always been." he pointed out. Dib didn't look any taller to him.

"Hm..." Keef tapped his chin. "We should probably check." The curly red headed boy went to the back of the classroom and grabbed a yard stick from the bottom of the shelf. He ran back, and positioned the two boys back to back. He stood the wooden yard stick up next to them.

"Yep, he's got exactly one millimeter over you.

"What?!" Zim shouted in disbelief. There was no way Dib was taller than him. There had to be some mistake.

"You shouldn't be so surprised Zim." Dib said, arms folded and a triumphant look on his face. "After all, humans grow to be taller than irkens. This millimeter is just the beginning! I bet by the end of this year, I'll already have several inches above you! I'll be bigger! Stronger!"

"Like some kind of alpha human!" Keef gasped excitedly. The both turned to look at him strangely.

"Um... no." Dib responded slowly.

"C'mon, nobody even uses millimeters! It only makes you taller than me in Canada." Zim said stubbornly.

"Sorry Zim, bt when it comes to height, it seems you got the short end of the stick! Ha ha ha ha! Yeah!" his fist shot in the air victoriously at his joke. Then a dark shadow formed on the ground, and out of the dark and swirling vortex of pain and restlessness, Ms. Bitters rose.

"I was awoken by the sound of mockery. Where is it? Show me the object of ridicule." the scary teacher ordered.

"I'm taller than Zim!" Dib said proudly.

"-by one millimeter!" this would not be a victory for Dib. One millimeter should be nothing!

"Hey, dont get... short with your friend." she chuckled darkly. Ms. Bitter's laughing was the most terrifying thing you could ever see or hear in your mortal life.

"Ms Bitters. I hope you don't think... little of him!" Dib smiled.

"Yeah!" one of the students chimed in. "And, uh... he's short!" A good portion of the class began to laugh as Zim walked dejectedly out of the room, opposed to his usual march.

"Guys, maybe you should lay off a tiny bit." Keef remarked.

"Ha! Tiny! Even Keef is in on it now!" Brian, one of the Skool Children laughed, hitting him on the back.

"N-no, that's not what I meant."

"Zim will forget. He's got a 3... 2... 1..." Dib counted down on his fingers.

"Short term memory!" everyone shouted, loud enough so that Zim, who was already down the hall could hear them. He clenched his fists and continued walking.

"Stupid Dib. I'm not short!" he reached up to undo the lock on his locker, but couldn't quite reach. He jumped a couple times trying to grab it.

"Oh come on!" he shouted angrily before taking a laser gun out of his pocket and just shooting it.

"There's got to be some way to get taller. Maybe I can create a growing device." he thought out loud, taking out his books.

"But no, Dib would expect that, and would just blow it up to spite me. So if not technology, then what can I-" suddenly an idea popped int his head.

"Something Dib would never expect me to use! It's perfect. But where can I find something like that capable of what I want?" he put the books into his PAK before walking to the computer lab. He picked the lock on the door with his clawed finger, and went inside. He sat down on one of the cheap plastic chairs, and booted up one of the ancient computers.
