Rolycoly

Rolycoly (Japanese: タンドン, Tandon) is a Rock-type Pokémon introduced in Generation VIII, specifically in Pokémon Sword and Shield. It is known as the Coal Pokémon in the Pokédex. Rolycoly resembles a lump of coal, featuring a single orange eye on its head, four rocky bulges on its sides, and a larger, circular rock structure resembling a wheel at its base. This wheel aids in its movement across rough terrain. It's noted that in the Galar region, Rolycoly was once widely used in households for its coal, which could be used for cooking and heating. Rolycoly has two common abilities, Steam Engine and Heatproof, as well as the hidden ability Flash Fire. Steam Engine increases its speed when hit by Fire or Water-type attacks, while Heatproof reduces Fire-type damage. Rolycoly evolves into Carkol at level 18, and then into Coalossal at level 34.
