Legend of Zelda: Skyward Sword [SPOILERS]

 Spoiler

Are there those crustacean monsters with the medal shells in the quicksand? If that's what you're talking about, you have to drop a bomb on them to kill them, then use their shells to run across the sand to safe spots and repeat the process until you're at the other side.

GOD DAMN IT NINTENDO! I WOULD HAVE NEVER THOUGHT OF THAT!

and yes it was that exact spot I was talking about so thanks
