Disguised as the Big Bad Wolf, Robbie intercepts Stephanie in the forest on her way to meet Sportacus, setting her on the wrong path. With Stephanie out of the way, he feeds Sportacus a sugar apple and drags him to the AirShip, which he plans to send away - with Sportacus inside - forever! Will the LazyTown Kids figure out Robbie‘s plan and save Sportacus in time?!
