End Jellyfish: New Floating Mobility & Durability Mechanics

Add a new passive mob to The End dimensions—the End Jellyfish—offering a natural parkour mechanic for island traversal and a novel risk-reward item for gear maintenance. Mob Behavior & Sizes Small Jellyfish: Ambient, passive mobs that float freely across the void in small groups. Large Jellyfish: Stationary floating platforms with full block collision on top, allowing players to stand and jump on them. Connection Mechanic: When a player steps onto a Large Jellyfish, it begins moving toward the nearest Large Jellyfish to link up. Players can chain jumps from jellyfish to jellyfish to navigate the void before acquiring an Elytra. Drop & Crafting: Jellyfish Slime Function: Used in an Anvil to coat tools, weapons, and armor, granting a +25% bonus to maximum durability. Trade-off: Equipment coated with Jellyfish Slime increases the base XP cost for all future Anvil repairs by +50%.
