Walltula

Haunting the vegetation of Ocarina of Time and Majora's Mask 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, forcing it to fall off the vine onto the ground. The Skullwalltula resembles a Gold Skulltula in appearance (other than skull plating, which resemble normal Skulltula), and they also make the same sort of scratching sound. They can easily be dispatched with a Hookshot, Longshot, Boomerang, or Fairy Bow. It is usually necessary to dispatch these creatures before climbing up a vine, as their scurrying attack is extremely hard, if not impossible in some places, to avoid.
