Skullwalltula

Skullwalltulas are Skulltulas that have attached to a wall which can be climbed, such as a wall with vines or rocks that can be scaled on it. If Link climbs the wall and approaches the Skullwalltula, the enemy will crawl towards Link, causing him to fall off the wall and back towards the ground. This means Link must kill any Skullwalltulas with the Fairy Bow, Slingshot, or Hookshot before attempting to climb the wall. When they are about to attack they flash red but if Link stops moving untill they turn away then he can continue without injury.
