When the Mayor hears that Bobby Bird is coming to town, he tries to call him but instead Robbie gets the call and pretends to be him. He challenges Ziggy, who is terrible at basketball, to compete against him. But Ziggy practices and gets support from his friends and "Teddycus." But Robbie switches Ziggy's teddy bear with a mean Teddycus which hands him bad support.

The kids are having a sleepover and the mayor tells them a bedtime story about a baby troll. Ziggy decides he wants a pet troll so the kids venture into the mountains and find a troll named LuLu who begins to eat all of the sports equipment. Much to Robbie's delight, he disguises himself as a troll catcher as he thinks a bigger troll will eat more sports equipment but will the kids be able to return LuLu back home before she eats most of LazyTown?
