Lanmola

A Lanmola is a powerful, centipede-like foe found in several Zelda titles. While they were originally common enemies, they began to serve larger roles in subsequent games in the series. The original artwork shows them as having an elongated segmented body, with four appendages per segment (making them more similar to millipedes than centipedes) and a single eye complete with iris; later games show them as clearly having two compound eyes, and two appendages per segment, making them more similar to centipedes.

The Legend of Zelda
In The Legend of Zelda, Lanmolas are only found in the Skull Labyrinth and are powerful foes. They come in red and blue varieties, with the latter ones being faster. Like the Moldorms in the game, grow shorter by one segment with each blow. They can be easily defeated with Link's sword.

A Link to the Past
Three Lanmolas guard the Pendant of Power in the Desert Palace of A Link to the Past. In this game, they hide underground and occasionally surface to attack, then return to the underground. When they burrow out of the ground, they send bits of rock flying in several directions. The sword is the most common method of dealing with them; however, arrows and the Ice Rod are both effective as well. After two are defeated, the last one will begin to move faster, and creates more bits of rock upon surfacing. Once the final one has been taken care of, Link gets the Pendant of Power and a Heart Container.

They later return in Ganon's Tower, where they are fought the same way as before. This time, however, there are stone face statues in the room that will occasionally fire beams at Link.

Both Twinmold from Majora's Mask and Molgera from The Wind Waker are similar in appearance to this boss.

There are also smaller Lanmolas found in the swamp area outside of the Misery Mire which act as regular enemies, as well as Swamolas in the Desert Palace.

Link's Awakening
In Link's Awakening, a Lanmola guards the Angler Key in the Yarna Desert. It attacks in the same fashion as those encountered in A Link to the Past, but this time it fights in a patch of quicksand. If Link sinks into the center of the pit, Link will fall into a cave and, after returning, all damage dealt to the Lanmola will be reversed.

One of Nightmare's forms is a Lanmola that is fought differently.
