S2, E2: Gogo Gorilla has hurt his hand while playing. Unfortunately the vet Dr. Zoolittle is away. So Benjamin treats poor Gogo. He does it so well that the Zoo director makes him the new veterinarian. When the zoo gets a new inhabitant - Dusty the African Desert Fox - Benjamin should vaccinate him against the "African Hickhop": an infectious illness that makes you hiccup and hop. But Benjamin didn't listen to what the Zoo Director said and next day the whole zoo is hicking and hopping.
