It's carnival day in Treetopolis and Tom gets more than he bargains for when he uses magic to make himself funny. When he joins Twigs' comedy act, Tom's magic causes him and his friends no end of trouble as they try to reach the courtyard to perform their acts to win the Carnival Crown. The Mushas want to win the crown and splatter the sprites with boohoo berries too and Tom has his work cut out to stop them as no-one can stop laughing for long enough to help him!
