Stephanie and the LazyTown children decide to repay Sportacus for all of his heroics by giving him a day off - with Stephanie taking over as hero. Robbie Rotten decides to take advantage, and builds a nasty dog which runs amok in the town.
A pink-haired girl named Stephanie moves to LazyTown with her uncle (the mayor of LazyTown), where she tries to teach its extremely lazy residents that physical activity is beneficial.
This show features the LazyTown characters in short, humourous sketches whilst Ziggy visits the UK to encourage healthy eating and getting active.
