To stop it from conquering the planet they injected human brain cells from an incompetent weirdo into a seperate mouse and then put the two mice in the same cage so the silly mouse will always frustrate the terrifying genius mouse’s plans

I wonder what they’re doing tonight

The same thing they do every night.

You Do realize the terrifying “genius” mouse’s plans always failed on their own, and it was the silly mouse’s plans who always worked until the terrifying “genius” screwed them up, right? Like, the opening theme song doesn’t actually tell you which one is the genius and which one is insane.
