Let me start by saying I almost returned this book as soon as I got it. All it says it DUDE. But then I saw my Husband reading it "with" our 4yr son. And they love it. Laughing with each other the whole way through. This definetly a springboard book because after that my son starting picking it up on his own and reading it. Then he began explaining to me what the shark, platypus where upset about. I really sparks the imagination of young boys ( and dad's apparently ) And opened my son up to more books. Just get it, you might not understand the appeal but trust me your son will.
