My idea is that there should be a jell-o biome with bouncing mobs and springy blocks. you should be able to only break them with a shovel. You can dye the blocks and mobs with food dye by putting sugar and a dye in the crafting bench. by making a ring shape with 4 iron ingots you could be able to make a trampoline frame and putting a trampoline frame in the middle and jell-o blocks around it you can make a trampoline. with a torch next to a jell-o block, you can make a jell-o lamp. jell-o creepers can explode and cover you in the stuff and makes you have the slow effect and jell-o bombs would do the same thing. by putting a stick and an iron ingot above it, you can make a spoon and eat the jello everything! It would give you speed and haste for eating it, but would only heal 1 hunger per block. By making armor with jell-o blocks, you could wear the armor and basicly have the thorn effect, but instead of hurting it, it would have knockback. thank you for reading this I hope it sparks great ideas! I think that this mod would improve minecraft because it would help you be able to jump higher!
