This is the area in the game where the player can find the final Powerpuff Girl Buttercup, dressed as her alter ego "Belladonna" (originally thought to have been lost after a recent battle with Mojo Jojo before Fuse's arrival) in the Past alongside Gang Green Gang member Ace. Here, she hands out a mission to the player to pass the word to the other Powerpuffs and the Professor that she is alive and well.
