Walltula

Skullwalltulas haunt the vegetation of The Legend of Zelda: Ocarina of Time and Majora's Mask (although only one appears in the entire game of MM). This arachnid creature clings on vines, waiting for enemies to climb up. If the enemy is deemed hostile or a threat, the Skullwalltula will flash purple and scurry over to the target, knocking it off the vine. The Skullwalltula resembles a Gold Skulltula in appearance (other than the skull plating, which resemble normal Skulltula), and they also make the same sort of scratching sound. They can easily be dispatched with any ranged weapon, including the Hookshot, Boomerang, and Bow. It is usually necessary to destroy these creatures before climbing up a vine, as their scurrying attack is extremely hard, if not impossible in some places, to avoid. Skullwalltulas are a rarity in Majora's Mask. They only appear in a nearby hole near the giant tree with Skullkid's etchings in Termina Field. The hole is used to play a tribal song (Sonata of Awakening, Goron Lullaby, New Wave Bossa Nova, or Oath to Order) at the giant gossip stone in the hole and the other corresponding giant gossip stones in order to obtain a Piece of Heart. Some spiders in Twilight Princess can be found clinging onto vines or ladders. Even though they act a lot like Skullwalltulas, they are called Walltulas, since they don't have the skull embedded on their backs.
