The Monsters on the Bus is a Sesame Street storybook featuring Mr. Johnson. The book presents a Sesame version of the childrens' song "The Wheels on the Bus." It's raining in the city, and Mr. Johnson gets on the bus (driven by Zoe), which is full of monsters. Ingrid and Humphrey are taking care of Baby Natasha, who spills the contents of her bottle over Mr. Johnson. Grover complains that the man's umbrella is dripping on his edition of Monster News. He finds another seat next to Cookie Monster, who's munching on a bag of cookies. A giant monster carrying a noisy boombox sits in the seat on the other side.
