Swamola

Appearing only in A Link to the Past, Swamola is a swamp worm that appears outside of the Misery Mire dungeon, in the Swamp of Evil in the Dark World. It appears to be related to a Lanmola, but it is much smaller and weaker. However, unlike Lanmola it has pincers at the front of its head with which it can cause a lot of damage. It leaps from the slime of the swamp looking for food, and will bite at Link before dropping back into the swamp. It shares its home with Kus.

Trivia

 * The Japanese name for the Swamola is Moldorm, while the Japanese name for Moldorm in most games is Tail. Swamolas behave much like the Moldorms of Twilight Princess. It is possible that all "Mol" enemies are related, or named as such for their worm-like qualities.
