Little Wolf’s Book of Badness [PDF ebook] 

Little Wolf has been brushing his teeth without being growled at, he’s been going to bed early, and he’s been far too nice to his baby brother, Smellybreff. His parents, concerned they will never make a beast of him, send Little Wolf off to Cunning College, where his Uncle Bigbad instructs timid cubs in the rules of badness. Will Little Wolf earn his BAD badge? Or will his uncle Bigbad HUFF and PUFF and turn Little Wolf into a sausage sandwich?
