The Powerpuff Girls Movie

Corrected entry: When Professor Utonium is arrested, the girls try to walk home, and eventually end up in Townsville, looking at all the destruction and such. Now, both Pokey Oaks Kindergarden and their house are in the suburbs, so how did they get into the town?

Correction: Because, as the professor says, they are just little girls. They have no idea where their house is so they get lost because they do not realize they are going the wrong way.
