Peepers is a watchdog, a creature with a large eye for a head with a red/purple iris. He has a lightning bolt mark on his black uniform and wears red gloves and shoes. Despite its resemblance to the common Guard Dog, it outranks them due to the pointed helmet on its head that other Guard Dogs lack, which gives it an aggressive appearance. Peepers has pink skin under his uniform and is in very good physical shape for his size.
