Little Bunny Foo Foo: the Whole Story

We all know the song about Little Bunny Foo Foo (LB) and how he bopped mice on the head. Why did he do that though? Did you ever stop to wonder? LB's life wasn't as happy and carefree as it seemed. He had secrets, and he had a hard life. He did get turned into a Goon for the choices he made, but what happened after that? What did he do and where did he go after that? Did anyone help him or did LB end up staying a Goon forever?
