When Genoveva opens her magic book, the screen is filled with feathers, beaks, horns, legs, wings, and snouts. Genoveva's magic book transports her to various habitats where she learns about the animals that live there. In this episode, Genoveva visits with a four-legged animal as big as an alligator. It has a huge mouth and a strong jaw. It has scales, but it's not a fish. What could it be? Welcome to the caiman's world.
