does obey and avoids jumping on his bed. But even though Walter tries to stay away from jumping on his bed, he has a second thought. He (although trying to stay away) thinks to himself that if Delbert gets to jump on his bed, he (Walter) can too. Because of that, Walter decides to have just one more jump himself. But instead, he keeps jumping higher and higher. His hair brushed through the ceiling. After one too many jumps, the floor starts to crack. He and his bed fall into Ms. Mabel Hattie's dining room; where he lands in her plate of spaghetti and meatballs. When Ms. Mabel Hattie (called "Ms. Hattie" in this book; but "Ms. Mabel Hattie" in No More Water in the Tub!) finds Walter in her plate of spaghetti, she says that she did not expect her company for dinner (with a mouthful of meatballs). Walter and his bed continue to fall, along with Ms. Mabel Hattie and the spaghetti, into Mr. Matty's TV room where he is watching the dinosaurs on his television set. Ms. Mabel Hattie falls into Mr. Matty's lap, while Walter lands in his fish tank. Walter wanted to stay up late and watch the dinosaurs. But his bed crashed through the floor taking the television with it. The next stop for Walter's bed and the ever-growing crowd is Walter's Aunt Batty's room. Mr. Matty's TV room was above Aunt Batty's room. Aunt Batty is still unpacking from her move to her room when she sees her nephew crashing through her ceiling. Aunt Batty's stamp collection gets scattered all over the floor. Aunt Batty and her stamps join the group as it falls into the next apartment, knocking over a castle of toy blocks that Patty and Natty have been building. Patty, Natty, and Fatty (their cat) are added to the group as it falls down into Mr. Hanratty's apartment where he is painting a picture at his easel. Walter, Ms. Mabel Hattie, Mr. Matty, Aunt Batty, Patty and Natty, Mr. Hanratty, the cat, the paint, the spaghetti, the TV (with the dinosaurs), the fish, and various toys now land in Maestro Ferlingatti's concert room where he and his string quartet are practicing. They too join the tumbling crowd who all end up safely in the dark and quiet basement of the building. The crowd (except Walter and his bed) magically vanish
