|~ Mister Mustache, worried about Thomas who was tripped over by the crabs.|
Hercule Mustache the Walrus is a walrus who lives in Mossy Bay Island. He is the friend of Sidney the Seal.
He is a walrus with a purple nose and bushy eyebrows. He has a moustache as his name suggests.
Hercule Mustache is very grumpy. He usually moans about deeds a relationship has been doing. In his first appearance, Sidney and Snowbert get fed up with his behavior for all his moaning and complaining. His first conflict was with the puffins who are causing mischief around the island.
Usually, he is not always grumpy. He is very kind to one of the puffins by helping them. He is also very good at asking other animals for help such as Jamie.
