Unfreeze is a Shump in which the health and energy bar share the same space: getting more health will take over part of the energy, and vice-versa. Unfreeze is set into an alternate reality in which supremacist and intolerant Penguins, the Penguivels, represent a global danger. Hyper, an ace-Hippo-pilot, is the leader of the rebellion that is going to strike the ultimate blow against the Penguivels, and show them that there is no tolerance to intolerance.
