Animalia - The Catcher in the Rhyme

Alex and Zoe stumble upon a magic portal in the library and are transported to the world of Animalia, where animals can talk. Animalia is ruled by the Core, a massive organic orb. It has been malfunctioning of late, bringing instability to the kingdom. All the animalians are compelled to speak in nothing but rhyme. If they can't think of a rhyme, they freeze.
