History Main / GelatinousEncasement

** Perhaps the most famous and iconic example is [[ExactlyWhatItSaysOnTheTin the gelatinous cube]]. This nigh-{{invisible monster|s}} is a large cube of acidic ooze that unwary creatures are liable to walk right into. Those engulfed by a gelatinous cube have to make a successful Strength check to escape, or suffer a slow and painful death - though at least their dissolving remains will make the monster easier for others to spot.

* ''Film/DungeonsAndDragonsHonorAmongThieves'': To escape from the Highsun games, Doric urges the rest of the heroic party to jump into a gelatinous cube that is part of the MobileMaze, and thus lowered below the arena when the blocks retract. The move would be rather suicidal in most circumstances; Doric manages to save the group by making sure the tip of her finger is touching the edge of the cube, and then using Wild Shape to turn into a garter snake which slithers in the cavity left by her body, reaching the hole and escaping. She then returns to human form and pulls out her companions one by one, before the acid of the cube can digest them.

* In ''Animation/PleasantGoatAndBigBigWolf -- Animation/MoonCastleTheSpaceAdventure'', the first thing that happens to the goats' group when they land on the moon - which is depicted in this film as a LevelAte -- is that most of them are encased in different giant jelly desserts that happen to be where they land. They all emerge from the jelly desserts with no problem, but not without Weslie freaking out over some small jelly hands -- actually Mr. Slowy's -- chasing him before it happens.

* ''TabletopGame/DungeonsAndDragons'': Perhaps the most famous example, the Gelatinous Cube is an iconic monster that serves as a trap to be feared.

* ''VideoGame/SuperMarioBrosWonder'': In World 5's An Uncharted Area: Wubba Ruins, Badge Challenge: Grappling Vine I, and KO Arena: Fungi Funk, the player can walk on the firm surface of the goo and can ground-pound through it and wade inside the goo itself. The player can also begin wading through the goo if entered from underneath or from the sides. Even fireballs from the Fire Flower move through the goo as normal. Later on in Wubba Ruins, the player can pick up the course's Wonder Flower, transforming the player into a goo-like creature, which can swim inside the goo much more effectively (as well as move on the goo's surface itself).
