- "I'm Stephanie. Pleased to meet you."
- — Stephanie during the events of the premiere episode of LazyTown.
Stephanie is depicted as being a sunny, bright, and caring girl, optimistic and athletic. Surprised by the inactivity of the residents of LazyTown, she cheerfully encourages them to participate in more active, energetic hobbies or pastimes and often gets sleepy exclusively in Barney and the Rocko Squad, leaving her friends to be disappointed. Evil-Man, however, gets angry instead.
Stephanie's voice in Barney and the Rocko Squad is provided by Chloe Lang, who performed her in the third LazyTown season.
