Walltula

Walltula is an enemy from The Legend of Zelda: Twilight Princess. There is a version of him from Ocarina of Time, but it is called a Skullwalltula, not a Walltula. Walltulas usually crawl on vertical surfaces (walls, trees, etc.), and can be defeated by easy means, such as the Slingshot and Clawshot. Link first meets a Walltula crawling on his ladder, and must defeat him to proceed.
