For Gradews 1 to 3. Here's the description on back of book: New cub on the block! He's a goofy, goony-looking guy. His ears stick out. His teeth stick out. His fur sticks out. He's the goofiest, gooniest-looking guy you ever saw. He's Herbert Harold Armfoot the Third. And guess what? He likes Sister...a lot! When the other cubs start teasing Sister about her "boyfriend," she gets mad. How mad? If Herbert Harold Armfoot the Third doesn't watch out, he's going to be Herbert Harold Armfoot the Last!
