Arthur is excited about his new Bionic Bunny comic book, but he can't find a quiet place to read. Dad is vacuuming the bedroom, Mom is busy in the kitchen, D.W. is practicing ballet in the living room, and Pal wants to play. The only spot Arthur finds is in a tree, and his dad realizes just what Arthur needs-a tree house! Soon after, Arthur has a place to go with his friends, family, or when he just wants to be alone.
