Banner is the protagonist of the series; a young squirrel who wears a bell around his neck. Orphaned as a baby, he was taken in and raised by a cat. A fire in the first episode separates him from his adopted mother and he flees to the forest where he befriends the wild squirrels and learns to survive. His feline upbringing means he is braver and tougher than other squirrels. Rather than flee from predators he will often attack them head on, especially to save his friends.
