The series focuses on an 8-year-old pink-haired girl named Stephanie, the newest resident of the LazyTown community. She has moved to LazyTown to live with her uncle, Mayor Milford Meanswell, and is surprised to learn that all of her neighbors lead inactive lifestyles. With the help of an above-average hero named Sportacus, she helps teach the other residents how to partake in more athletic pastimes. Her attempts are often nearly thwarted by Robbie Rotten, who prefers to lead a sluggish life and is agitated by the sudden boom of physical activity. On a regular basis, Robbie devises ill-judged schemes to make LazyTown lazy once again. However, his plans are never foolproof and always end with him losing.
