Invader Zim Episode 3 - NanoZIM Episode Title:NanoZIM.Episode Description:Dib sneaks into Zim's base, takes incriminating pictures of Zim without his disguise on, and puts them on a floppy disk. Zim discovers Dib and shrinks to microscopic size to enter Dib's body. Zim accesses Dib's nervous system, giving him control of Dib's arms, and makes him crush the floppy disk. Dib reveals he has a copy of the disk hidden in his house, so Zim travels to Dib's brain to wipe the memory of where the disk copy is hidden, and, as an added bonus damage Dib's brain to the point where he will never be a threat again. Dib then swallows a mini-submarine (a creation of his dad's) and begins to fight Zim. When Zim accesses Dib's brain, Dib begins to lose control, and Gaz, who thinks this is merely an online game (and a lame one at that) takes over. Gaz saves Dib's life and organs from Zim, who is later disposed of, but never realizes that this was more than a video game. This episode also features more intense computer generated sequences. Computer-generated imagery had been used in the series already, but this episode was the most demanding so far.[5]
