In The Wind Waker
The Mothula is an enemy in The Wind Waker found in the Forbidden Woods. Not all Mothulas can fly, though they all can shoot out Morths, hampering Link's movement and making it difficult for him to attack. The flying variety will lose their wings to the Boomerang or will become stunned by a Deku Leaf blast, which allows Link to attack them. If you want to finish them in one hit use a fire arrow.
