Underground Ruins is an area located within Clay Tunnel, where Regirock, Regice, and Registeel can be caught. Their method of capture depends on the game version; Regirock can be found in either game after a puzzle is solved, while Regice is found with the Iceberg Key in White 2 and Registeel with the Iron Key in Black 2. The key unavailable in one game version can be transferred via the Unova Link.
If all three Pokémon here are caught, Regigigas can be captured in Twist Mountain.
