The Stone Statues appear in the original Metroid. They are used to guard Tourian and depict the likenesses of Kraid and Ridley, the two minibosses in the game. The statues are situated on a ledge above a pool of Acid. This prevents Samus from easily accessing Tourian. To get to the Blue Door leading to Tourian's elevator, Samus must defeat the two minibosses and then shoot the flashing statues. They will rise, and a bridge of Bomb Blocks will form.
