Rolycoly is a Pokémon which resembles a small piece of coal. It has a single orange eye, while the rest of its body is black. It has a rugged exterior and lacks any limbs. Its lower body has a wheel, which it rolls on and uses for movement.
Rolycoly was first discovered 400 years ago in a coal mine. It races around caves in the rough rocky terrain like a unicycle, burning through the red coal that sustains it. Its red eye can illuminate dark areas. Until about 100 years ago, every house in Galar had a Rolycoly. The coal it drops can be used for cooking and heating up homes. Rolycoly's popularity continues even into the modern-day, as it is used for outdoor activities. It is a natural enemy to Dwebble, as the latter tends to think that Rolycoly is an inanimate rock to turn into a home.
