The RowdyRuff Boy's end up in the same school as the Powerpuff Girls Z. At first it was about beating the girls but plans change when the new student counselor shows up and something odd happens to the people around them.
"So you're saying that we can destory stuff?"
"Did you seriously hear that from my mouth?"
"Too late! Boomer already put on his goggles and Butch put on his sweatbands!"
"Are you guys even listening to me?!"
"Yahoo!"

The girls always had a boring life, went to school, come home and repeat the process. But what happens if new boys move down the street?
Well trouble happens.
