La casa en el rbol de 13 pisos / The 13-Story Treehouse: Monkey Mayhem! [Hardcover]

Andy and Terry live in the best tree house on the planet. It has 13 floors and includes a bowling alley, swimming pool, secret lab, and a machine that shoots marshmallows into your mouth when you are hungry! The two have to write a book, but that's so hard to do when you need to deal with flying cats, mermaids, and a giant gorilla, just to name a few distractions!
