In the magical world of Gardenwall and other places where the majesty of nature and the freedom of animals reign supreme, Sir Biscuit Butterworth and his friends embark on exhilarating adventures to battle the mischievous Count Conrad the Cat, a vegetable-eating vampire rabbit named Fluffula, and a blue-tongued fox called Slendertail. Learning the virtue of friendship, Sir Biscuit comes to understand the real meaning of adventures: the friendships formed through them. Other courageous animals learn the importance of finding themselves and embarking on quests—like Geronimo the Mighty Mouse; Vulpes, the white fox; Tucker, a golden retriever with a special power to talk to the human he loves most; and an abandoned swan who is raised by a human family.
