After reading the Numpups' Super Numtum comic, Flinders wants to sand-board over the Heap of Adventure just like Super Numtum, but he ends up stuck in a mud pool! It's up to the Numpups to work out how to rescue him equipped only with sticks! The Numpups wonder what Super Numtum would do. Meanwhile Fluffy McTuffy is stuck in an extra-sticky jam slick of her own making and Super Numtum's super hero arm is too short to reach her. But will using his arm and one of Fluffy's skies mean the combined length is long enough to rescue her?
