Quicksand is a colloid hydrogel consisting of fine granular material (such as sand, silt or clay), and water. In the dimension of "Jumanji", Quicksand serves as a natural trap for herbivores or predators, leading to either drowning from total submerging or dying from exhaustion trying to drag themselves free.


Jumanji Steampunk Hippo Quicksand

The mechanical Hippo sinks in Quicksand.

Quicksand may be found on riverbanks, near lakes, in marshes, or near coastal areas. Quicksand forms in saturated loose sand when the sand is suddenly agitated. When the water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support the weight. Quicksand can form in standing water or in upwards flowing water (as from an artesian spring). In the case of upwards flowing water, seepage forces oppose the force of gravity and suspend the soil particles.

The saturated sediment may appear quite solid until a sudden change in pressure or shock initiates liquefaction. This causes the sand to form a suspension and lose strength. The cushioning of water gives quicksand, and other liquefied sediments, a spongy, fluid-like texture. Objects in the liquefied sand sink to the level at which the weight of the object is equal to the weight of the displaced soil/water mix and the submerged object floats due to its buoyancy.


After the Monsoon, the players set the "Jumanji" game up in the attic and carried on playing with Alan's turn. His dice roll triggered the appearance of Quicksand (which is actually created from the attic floor). Alan was instantly within the field and began to sink, his friends trying to pull him out to no effect because of the leverage breakages. Sarah finally laid on an old door and grabbed Alan to stop him from being total submerged, while Judy rolled her turn to try and resolve the situation, apparently ending the Quicksand effects entirely; but left Alan and Sarah stuck in the floor and unable to move. They were both rendered unmovable which left them vulnerable to persistent giant "Jumanji" Spiders, only backing off when Sarah's last turn unleashed an Earthquake, which tore the Parrish Mansion up and set them free from the floor.

In the Milton Bradley board game, Quicksand has its own danger card. Rolling an Axe on the rescue die within 3 seconds will defeat the Quicksand threat.

Quicksand appears in the animated series as dangerous environmental hazards, but it can also be a good method of chase evasion if carefully avoided. One such instance being in Master Builder; when Alan, Judy, and Peter were chased by one of Professor J.S. Heinrich Ibsen's steampunk Hippopotamus, which sank in quicksand because of its weight and inability to drag itself free.

In Ransom of Redhead, Nora Shepherd unwittingly steps into a pond of Quicksand against Judy's warnings, still under the impression she's dreaming, which she regrettably reconsidered after her ordeals in Jumanji.

In Night of the Hunters; Alan is nearly caught by the two hunters, but escapes while they're arguing and Van Pelt starts to sink in quicksand. Alan saves him after he tosses away the rifle, but regrets saving his archenemy when Van Pelt tries to kill him with a pistol and fails, pushing him back into the pond. Van Pelt managed to swim out of the Quicksand and quickly retrieved his rifle to continue the hunt.

In. Robo-Peter while fleeing Professor J.S. Heinrich Ibsen's steampunk robot duplicates of themselves, Judy gets stuck in quicksand so Alan and Peter have to rescue her. Then the robots get stuck and sink but grab Judy's leg to get free.
