Jelly is normally a wobbly, delicious food. But sometimes, characters in fiction can bounce on large moulds of jelly-like trampolines. Don't ask us how they avoid getting stuck in the jelly itself.
If the jumper ends up being trapped inside jelly, it becomes Gelatinous Encasement.
- In Jewelpet the Movie: Sweets Dance Princess, Paku bounces on some gelatin to eat part of the Candy Tower that is falling towards him and the rest of the gang. Eating said part of the tower is what awakens his true identity as a monster that is to destroy the building.
- In Cloudy with a Chance of Meatballs, Flint takes Sam to a large castle made entirely of jelly, and they have fun bouncing around inside.
- In Fun and Fancy Free, the Mickey and the Beanstalk segment had Goofy using a giant jelly pudding in that way.
- In the third Pleasant Goat and Big Big Wolf film, Weslie's gang is chased by some of the Bitter Gourd King's soldiers into the Jelly District, consisting of ground made entirely of jelly that the characters bounce on to outrun the soldiers. They reach a cliff in the District that they have to jump extra hard to pass over, but Wilie jumps on everyone else as they're in the air, sending them flying into a wall and falling to the ground below.
- In James Pond 2: Robocod, one stage is made entirely of jelly. The hero can bounce off the walls and platforms from all directions.
- Ratchet & Clank Future: Tools of Destruction has the Gelanator, which allows Ratchet to shoot out cubes made of a gelatinous substance, which he can use to jump much higher than normal.
- Banjo-Tooie has this show up in several places in the Cloud Cuckooland level. Generally, the form it takes is a round red jelly.
- Croc plays this completely straight, with rather out of place jelly trampolines.
- Sonic the Hedgehog:
- In the DS version of Sonic Colors, there are large domes of colorful gelatin in Sweet Mountain that, when landed on, bounce Sonic straight up or, if hit from the side, bounce Sonic in the opposite direction at full speed.
- Sonic Mania does this with the chemicals in Act 2 of Chemical Plant Zone. If the player stands on certain syringes, they will turn the chemicals below them into gelatinous surfaces that the player can bounce on. Blue surfaces create small bounces, and green surfaces create big bounces.
- The levels "Jelly Pipe" and "Torrential Maze" from Yoshi's Story feature bouncy jelly in a Down the Drain setting.
- There were several of those in social game Pet Society. The player's virtual pet could buy them in the shop and jump on them.
- The ground in The Floor is Jelly reacts like it's made of jelly, and is appropriately very bouncy.
- Donkey Kong Country: Tropical Freeze has 5-5, Jelly Jamboree. It is set in a jungle containing a factory that processes the jungle's tropical fruits into large cubes of delightfully bouncy jelly.
- Minecraft's Slime Blocks act slippery and bouncy, and completely negate Falling Damage if you drop onto them.
- Shovel Knight has portions of lava in Mole Knight's stage that can be temporarily converted into bouncy slime. There are also giant beetles with gelatinous backs that require Shovel Knight to bounce with them to cross hazardous terrain.
- Theme Park World features the Jelly Bounce Ride in one of the Wonderland levels. It's a giant trampoline shaped like a jelly mould.
- Rusty and Co. has an example in the paladin Madeline using Cube (a D&D Gelatinous Cube) as a long-distance trampoline, with the assistance of a rather long-looking drop in building momentum.
- Jelly World in Neopets is this trope exactly—very bouncy and very edible. There's even a game which revolves around bouncing.
- An episode of Dragon Tales had the gang mistake a giant mound of Wiggly Jiggly that Mungus the giant made earlier for his mother for a giant trampoline called a Bounceamount.
- In Phineas and Ferb, the episode "Day of the Living Gelatin" had the duo turn an entire swimming pool into one giant gelatin trampoline.
- Subverted in an episode of Ed, Edd n Eddy, where the Eds make a giant pool of gelatin. Ed dives in...and sinks to the bottom.
- This happens often in Tom and Jerry and other cartoons with mice.
- In True and the Rainbow Kingdom exists a location called Boing-Boing Lagoon where everyone can bounce on a Jelly-like lagoon, this can be seen in the "Wish gone wild" episode for example.
