One day Doctor Anton receives a letter from Goat. He takes his bicycle out to make a house call but runs into all sorts of trouble on his way.

Doctor Anton is a kind veterinarian who always wears a smile. All sorts of animals come to his clinic each day. A chicken rooster who lost his voice, a tiger with a tummy ache, an alligator whose jaw came unhinged... No matter how scary the patient may seem, Doctor Anton listen closely and cures what ails them. Even kids who hate going to do the doctor can enjoy reading about familiar animals.
