Fun with pink-haired Stephanie, an enthusiastic eight-year-old, and superhero Sportacus as they learn how to make healthy choices and get active. Sportacus shows the kids how to use an Energy Book to keep track of how much sports candy they eat, and how much exercise they get. Robbie hears about the book, and decides to wreck the kids' health plans by luring them into bad behaviour and giving them stickers for sweets instead. The kids realise their mistake and correct it by doing healthy things.
