What it’s about. When the happy little hippo, Mumbo Jumbo, accidentally turns giant his life changes for the worse - seemingly forever. Now Mumbo is forced out on a challenging journey in order to encounter an unpredictable witch. Luckily Mumbo's best friends join him.

It is not easy being a small hippo, nor a giant one, and when the only way back to normal depends on the cooperation of a frank and mischievous witch, anyone can imagine that it requires a true effort. Hopefully Mumbo Jumbo will develop a strong belief in himself during the adventure. Otherwise, it will definitely be an impossible mission.
