Read along with Disney! The other toys tease anxious Rex for being a party-pooper, but he's about to prove them all wrong. When Bonnie leaves him in the tub with the bath toys, Rex—the only one with arms to turn on the water, lights, and music and get the bubbles flowing—goes from party-pooper to Partysaurus. Follow along with the word-for-word narration, say "What up, fishes" to some new friends, and party along with Partysaurus Rex...before the whole house floods!
