Invader Zim Episode 30 - Megadoomer Episode Title:Megadoomer.Episode Description:Due to an angry prisoner who sorts packages, Zim is accidentally shipped a high-powered robot with a cloaking device and he immediately heads off to destroy Dib with it. The robot does not come with batteries, however, so every few blocks, the machine has to be plugged into a new power outlet to stay cloaked. What's more is that the robot is cloaked, but Zim inside is not, making him visible for everyone to see. (Also, the power cord isn't invisible, either.) When he gets to Dib's house the cloak fails and he destroys the robot so Dib cannot get any pictures of it.
