INVADER ZIM "Simon Says "Doom" Revised Premise 07/26/01 Dib's paranoia prompts him to volunteer for an after-skool charity program when he finds out that ZIM has already been participating in it for many weeks now. It seems ZIM has been playing with orphans after school and Dib fears ZIM has been up to something far from playful! When the orphans arrive at skool, Dib is assigned the title of filth cleaner and has to clean up after all the dirty little kids. Dib neglects his responsibilities in his blind pursuit of ZIM, as ZIM takes the kids all around the school for their various activities. Dib constantly does more destructive harm than good in assuming that EVERY thing ZIM does is part of some sinister plan. Dib is kicked out of the program for being a menace to the little orphans and watches as ZIM is rewarded for being such a good kid. Still resolved, Dib sneaks back into the school just in time to see ZIM playing SIMON SAYS with the orphans. But there's something funny about the whole thing. ZIM spots Dib and tells him he's too late, as his plan is already complete - He has discovered secret words that can control the minds of certain humans, and has already trained the little humans to be his army of obedient orphan soldiers. Dib watches as ZIM uses the "Simon Says" command to get the orphans to do his bidding. ZIM gives the command "Simon Says conquer the earth for your Master - ZIM!" The orphans, not really trained at all, begin to totter about, eventually drifting out into the streets. Dib tells ZIM that his plan is stupid and that the orphans can't do any damage. Mr. Elliott enters and wonders what happened to all the children and why Dib is still around. Dib gets blamed for the children being gone and is expelled. ZIM, seeing the orphans are just playing around outside, decides the plan was ingenious, but that humans are just stupid.
