MobMorph

MobMorph lets you become any mob in Minecraft. Kill a mob to unlock its morph, then transform into it with a single key press.

  Every morph comes with a unique G-key ability that matches the mob’s vanilla behavior. Creepers explode, Ghasts shoot fireballs, Endermen teleport, Witches throw potions, and
  much more — every single mob in the game has its own ability.

  Morphs also come with passive abilities. Fly as a Bat, Ghast, or Phantom. Breathe underwater as a Dolphin or Axolotl. Climb walls as a Spider. Walk on lava as a Strider. Slow
  fall as a Chicken.

  Your hitbox changes to match the mob you become, letting you fit through tight spaces as small mobs.

  Features:
  – Morph into every vanilla mob in the game
  – Unique ability for each mob activated with the G key
  – Passive abilities like flight, water breathing, wall climbing, lava walking, and more
  – Custom hitboxes matching each mob’s size
  – Mob-accurate movement speeds for every morph
  – Menu for quick morph selection
  – Animations synced with player movement — walking, swimming, flying
  – Predator mobs will hunt you if you’re morphed as their prey
  – Undead morphs burn in sunlight just like the real mobs

  Controls:
  – J — Open the morph menu
  – G — Use morph ability
