Lanmolas

The boss of the Desert Palace is three Lanmolas. They travel under the sand and now and then burst out of the ground. That is when to hit the head, their weak spot, with the bow or the Ice Rod, but the timing is tight and hard until you are used to it. For damage that is small but sure, hold the sword out over the spot where the sand is heaving up.

It bursts out of the sand and goes back into it. A caterpillar-like boss; three of them mill about in a small room. Watch out for the sand grains that fly when they come up. Cut and run, over and over. Planting lots of bombs also works.

Sand worms that burst out of the fine sand. There are three of these too. The sand grains they scatter as they come up are the nuisance, but the grains always fly the same ways. Wait right under the spot where a Lanmola will come up, and when it does, cut it hard with the sword. If you would rather not get close, plant bombs and watch. The only thing to fear really is the sand.
