Jellyfish are small tamable mobs.

Spawning Edit

Jellyfish spawn in water between layers 46 and sea level, and can be found in any biome.

Drops Edit

Jellyfish will drop 0-2 slimeballs upon death. This can be increased with the Looting enchantment. They drop 1-3 experience when killed by a player or tamed wolf.

Behavior Edit

Jellyfish underwater

A jellyfish swiming underwater.

Jellyfish are passive mobs, and will not attack or chase after you. They are translucent, and move in a pulsating manner. They are also luminescent at night. It takes about 6 seconds before jellyfish take damage when exposed to land.


Jellyfish will typically spawn using one of five different colors: including light orange, purple-grey, light blue, green, and orange-red. There are also seven other colors, but jellyfish with these colors do not spawn naturally. These include orange-yellow, speckled blue, white, purple, blue, orange, and white.


If you touch a jellyfish, it will give you the Poison I effect for five seconds on Easy or higher difficulty.


  • Jellyfish are not very dangerous mobs, just avoid touching them.
  • They have very low health; a stone or iron sword will kill them with one strike.
  • Stay away from areas of water where jellyfish may be lurking in.

Taming Edit

A jellyfish can be tamed by using a fish net on them and then releasing it again. Once the jellyfish has been released from the net, the naming screen will appear. A tamed jellyfish cannot be healed by 'feeding' it with food items, they can only be healed with a splash potion of healing. Tamed jellyfish will not poison the player when touched.

 History Edit


v10.0.4 Edit

- Fixed jellyfish crashing bug.


Jellyfish and stingrays will no longer poison players riding a boat.

v5.2.4 Edit

- Fixed GL post render error with jellyfish. Note: this currently removes transparency.

Jellyfish and stingrays will no longer poison players out of water.


- Added jellyfish. 

Trivia Edit

  • As of v4.5.0, when jellyfish models were revamped, there were seven other models that were implemented, but never used. The missing jellyfish textures can be found in the mod files.
    • Despite being missing, the jellyfish can still have these models, with the use of mods that can alter their appearance, such as an in-game NBTEdit.
  • Jellyfish are the only passive mobs in Mo' Creatures that poison the player.
