I have an Invader Zim episode stuck in my head...

[msfledermaus]

...the one where Zim's class gets Pipi the hamster, and Zim tries to turn it into a giant (but cute) force of conquering destruction and instead makes a giant Godzilla-like creature called Ultra-Pipi and all Hell breaks loose....

*siigh*

Go, Ultra-Pipi, go!!!
