Jack and Annie are on the playground at recess when they feel the magic tree house calling them. They sneak away and are whisked off on an adventure in South Africa, where a majestic rhino needs saving! There are a swooping helicopter, strict park rangers, and--most terrifying of all--poachers. How do you hide one of the largest land mammals in the flat terrain of the African savanna? Jack and Annie are going to need a little bit of magic for this mission!
