Hadley the Hippo is hungry, and she won't rest until she finds something to eat. But as she walks through her jungle home, she finds that the snacks in the jungle have an odd effect on her-they change her color! Still, Hadley munch, munch, munches her way through the greens, blue, purples, oranges, reds, and yellows of the jungle, hoping to finally satisfy the rumbling in her tummy. Along the way, she finds that it really does matter what you consume.
