Maya's big birthday celebration is coming up and JoJo has her present all ready - a toy calliope. As it turns out, Maya and Mr. Muscles are arriving with a real calliope that Mr. Tickle ordered and JoJo hurries to hide the present. Then she ends up sitting on it and it's completely ruined. JoJo's despondent, but then Mr. Tickle has a great idea - JoJo can play Maya's favorite song on the real calliope. JoJo quickly warms up to the idea, but it'll take her a lot of practice to be ready for the party in two days, so she has to stick with it.
