[Zim, wearing his fiendishly clever human larva disguise, sits in his desk at skool. All students appear to be present. Zim's eyes dart around the room. He twitches repeatedly.]

ZIM: [to himself, spastically] The dreams. The dreams keep coming. Nightmares! The screaming. I can still hear the screaming. NO! These dreams won't beat me. If they won't stop coming, I'll play their game. I'll beat them! I'll show you!
MS. BITTERS: Doomed, doomed, doomed. Your assignment today is on --
ZIM: I CAN'T TAKE IT ANY MORE!!

[Zim leaps from his seat to stand atop his desk. He tears off his wig and his contacts, tossing them to the floor. A collective gasp.]

ZIM: You see?! I am an alien! An invader!! I will RULE your filthy planet!! How do you like THAT?!

[A long pause.]

ZIM: No, seriously.

[Everyone freaks out. Screaming, running in circles, thrown desks, the works. Zim stands outside the chaos, laughing maniacally as only Zim can.]

CHUNK: Oh my god!
ZIM: You are intimidated by my spectacular true form, are you not?!
CHUNK: Oh my god! Dib was actually right!!
DIB: Hey!

[Ms. Bitters reaches underneath her desk. Her hand hovers over buttons marked "Insane Student", "Lice", "Death", "Blue Alien Invader", and "Red Alien Invader" before finally pressing a button marked "Green Alien Invader". Immediately a squad of trained alien-tracking ninja crash through the windows. One of them lands on Spoo's head.]

ZIM: Bwahahahahaha!! I fear no ninjas! Bring yourselves to my presence! You shall be annihilated in a very squishy fashion!

[Cue the flashy action sequence! Zim's spider legs extend from his pak, and he leaps from his desk, smacking two of the ninja together with his forelegs. A ninja slashes one of his legs off at the first joint; he retaliates with a laser blast. Three ninja leap at Zim, who picks up Dib and knocks the ninja away with him as if he were a baseball bat. Finally the ninja work together, slashing Zim's legs to pieces and grabbing him by his arms and legs.]

ZIM: Hah! Do you believe that I am fooled? This is another nightmare, nothing more! I will wake up safe in my pathetic little Earth bed! Nothing you can do to me will --

[A ninja smacks Zim upside the head. He immediately loses consciousness.]

NINJA: Shaddup.

[Close-up on Zim's face.]

ZIM: [wakes up, screaming] AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHH!!! [pant, pant] Yes, just as I suspected. It was all just another... stupid... night... mare...

[Zoom out, to show that Zim is strapped to an autopsy table in a dark, scary laboratory.]

SCIENTIST: We are preparing for the initial dissection...
ZIM: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHH!!!
