Dib sneaks into Zim’s base, takes incriminating pictures of Zim undisguised, and puts them on a floppy disk. Zim discovers Dib moments after the pictures were taken and shrinks down to microscopic size to enter Dib’s body via microscopic submarine. Zim accesses Dib’s nervous system, giving him control of Dib’s arms, and makes him crush the floppy disk. Dib reveals he has another copy of the disk hidden somewhere in his house, so Zim travels to Dib’s brain to wipe the memory of the disk’s location, and, as an added bonus, damage Dib’s brain down to the point where he will no longer be a threat again. Dib then swallows a mini-submarine, created by his father, and begins to fight Zim, using controls that look uncannily like a laptop. When Zim accesses Dib’s brain, Dib loses control, and Gaz, who thinks this is merely an online game, begins to fight Zim. 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 features intense computer generated sequences. Computer-generated imagery had been used in the series, but this episode was the most demanding.
