Morth

Morths are enemies that appear in and. They are immature Mothula, often found in swarms. These enemies will swarm around Link and attempt to latch onto him, which will slow his movement considerably. Although while generally harmless on their own, the slowed movement can give an advantage to nearby enemies and possibly put Link in harm's way of hazards.

The Wind Waker
In The Wind Waker, Morths mainly appear in wooded areas, most commonly in the Forbidden Woods. They will close in on Link whenever he moves close, and if several Morths latch on, they will hamper his movements. Link can easily free himself by performing a Spin Attack or just by rolling. They are easily dispatched with the Sword and the Boomerang if they are not latched on to Link. Morths are also occasionally released by Mothulas as well.

Although usually seen as a hindrance, there is one area in which Morths can actually be somewhat helpful; a certain room within the Forbidden Woods houses many thorned Vines that erupt from the ground in certain places, effectively forming a maze where Link can be damaged if he moves too hastily. If enough Morths are attached onto him, however, they will force him to move slowly through the room and thus lessen his chances of accidentally making contact with the vines. Large numbers of Morths are first encountered in the chamber preceding this one, possibly indicating that this was their intended purpose.

Tri Force Heroes
In Tri Force Heroes, Morths appear in certain Levels of The Dunes area, and in the Desert Zone of the Den of Trials. Unlike the Morths of The Wind Waker which move individually, Morths are always groups of three, and will immediately slow down the Link they manage to attach to. When attached, the Morths prevent the Link from dashing. Morths cannot be removed by the Link they are latched onto, instead another Link can free him by attacking the Morths with his Sword or with another item. Morths often appear in areas with a lot of sand, which makes them very dangerous as their slowing grip can potentially make their host susceptible to sinking in quicksand. Morths will also respawn shortly after they are defeated. They often appear in Stages where all enemies have to be defeated, however Morths are not counted. They will disappear completely after clearing these Stages.

Morths will die if an afflicted Link steps onto an active Triforce Gateway. Morths that attempt to attach onto a Link wearing the Cacto Clothes will die immediately.
