High above the jungle floor, fearless Zoe, explorer extraordinaire, catches a glimpse of the rare, wild Addiebeast. She springs over the treeline in hot pursuit, and then Zoe's mother calls, "We're leaving in five minutes!" Yet Zoe still has so much to do on the playground, which transforms into a jungle in her imagination! So against the ticking clock of Mama's countdown, she chases the Addiebeast across precarious logs (balance beams), escapes from wild monkeys in their natural habitat (the jungle gym), and climbs to the very top of the rainforest (a tree house). But can she catch the elusive creature in time?
