Because she is being mean, Timmy wishes that Vicky was nice, but a malicious spider-like bug that causes her to be mean gets on the loose and starts to target his dad, Principal Waxelplax, and almost the President. Timmy manages to get the bug back in Vicky's body, but Cosmo reveals he borrowed the President button machine, and when he presses it, he accidentally causes the dwarf planet Pluto to explode.
