This week we meet star performer Rory the Duck, whose swollen leg has kept him out of show business for way too long. Meanwhile, two representatives of endangered species, Krypto the Onager and Unga the Bonobo, are given a new lease on life under the gentle care of the zoo vets. And Zucchini the Beaver's overgrown teeth are brought down to size. We'll discover these stories and more, as we go behind the scenes at the Columbus Zoo and Aquarium!
