What if Bunny's Not a Bully?

Gertie the elephant says everyone on the playground should stay far away from Bunny because she's super mean. But Kitty has questions: How did Bunny become a bully? Was she born that way? Was she stung by a bullybug? Or maybe she caught the bully flu? Wait, does that mean bullying is contagious? And if it is, couldn't the other animals catch it, too? But... then no one would play with them either, and that doesn't seem fair. Is it possible that Bunny is sorry? Should they give her a second chance?
