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.

Quicksand appears in Yarna Desert.

The Legend of Zelda: Ocarina of Time
The first trial of the Haunted Wasteland, the River of Sand, is a river of flowing Quicksand. Link must use the Hover Boots or Longshot to cross the river. Quicksand also appears in the Gerudo's Training Ground.

Quicksand appears in various areas throughout Labrynna and Holodrum, most notably during the Big Bang mini-game and in Samasa Desert.

The Legend of Zelda: Twilight Princess
Quicksand slowly causes Link to sink. Poison Mites can latch onto him at this time, making it more difficult for him to successfully cross the sand. Link can use the Spinner to avoid the effects of Quicksand. In heavy contrast, the Iron Boots cause him to sink immediately.

Gongoron can be controlled to roll over Quicksand with ease.
