Things aren't going well for the Puku species and it's all thanks to Ollie. When Ollie was little, he disobeyed his father's advice to stay away from other animals and taught a Javan how to open and eat piplets. This act of kindness quickly gets out of hand and leads to the Javan stealing all of the piplets from the Pukus, leaving them with nothing. Ollie tries to make things up to the others by scaring away the Javan. All goes well until one Javan rebels and crashes into Ollie, causing him to fall down a hole and crash into a magic pod. When he wakes up, Ollie realises that he has become a Javan. Fortunately, there is another pod nearby, but before he can get to it, Ivy, the Javan from earlier, touches it first, turning herself into a Puku. Fully swapped, the two must work together to navigate through the valley and find more pods, while figuring out the benefits of this transformation.
