There's a new Powerpuff Girl in town...or so she'd have you think! Her fiendishly foul plot: to trick Santa into turning her into the fourth Powerpuff Girl!

"The Pee Pee G's" When the Girls wake up to discover their bed is wet, none want to admit that they are the guilty party. "Boy Toys" Princess interrupts a battle between the Powerpuff Girls and the Rowdyruff Boys. She tries to join the Rowdyruff Boys but they reject her, so out of pity the girls let Princess become a Powerpuff Girl.
