In "Arthur's Tree House", 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. This gives his dad an idea. Soon Arthur has his very own tree house, where he can go with his friends, family, or just to be alone!
