Quicksand

Quicksand is a recurring obstacle in the Legend of Zelda series. Unable to support significant weight, Quicksand will generally suck Link in if he crosses over it. Sometimes this will lead to his demise, while other times, it transports him to an underground area that he must navigate his way out of.
