Bounce Houses? Yes, please Jungle theme? Of course. Cake with artificial flavors and colors? You bet. These treats are all part of Bobby's party crashing experience. Bobby Birthday (yes, his last name is Birthday ) loves going to birthday parties even when he's not invited. He samples the food, peeks at presents, bounces on inflatable elephant trunks, all the while escaping his mom's healthy cooking. Then one day, Bobby meets a boy named Teddy who only has grown-ups as guests. As Bobby talks to him, he realizes his party crashing can serve a much better purpose -encouraging friendship no matter what our differences may be.
