Not Another Buttercup is a gamebook; the twenty-second in the Powerpuff Girls Plus You Club series.


Mojo Jojo has stolen some Chemical X, added sugar, lots of spice, and nothing nice, and used the mixture to create Bittercup, an evil Powerpuff Girl! What's worse is that Bittercup looks exactly like Buttercup, except that the bad girl wears a black dress and has gray eyes. Now Bittercup is committing crimes and causing trouble all over Townsville—but everyone thinks that it's Buttercup who's responsible! Can Buttercup stop her evil twin before her reputation is ruined forever?
