"Hamstergeddon" is the second segment of the ninth episode of Invader Zim.


Zim's classmates get a new hamster, peepi. Zim also decides that its cuteness can be used as a form of mind control. So he attaches a device to Peepi which causes it to enormously mutate and develop several superpowers, such as the ability to fire a laser beam from its mouth. Unable to control it, Zim instead allows the hamster to rampage throughout the city. But when the hamster heads for Zim's base, Zim is forced to team up with Dib and use alien technology to launch the creature into deep space.
