The Jellyfish is a tier 3 animal.



Passive Abilities[]

  • You poison anyone who makes contact with you (except for animals that are immune to poison or have friendly fire turned off for you).
    • However, you can poison whales when they absorb you.
  • You are immune to poison.
  • You move sporadically. Hitting opponents when bursting to deal higher damage.

Suitable Biomes[]

  • The jellyfish is suited to every biome (at least in FFA), apart from those where no-one else can survive (such as the extremely salty pool and the oceanic rift, both in the deeeep abyssal plain, where they'll lose salinity, temperature and pressure). Before, it wasn't suited for the swamp and swamp surface.


This is a complete list of food that jellyfish can eat.

Name Can be eaten by Image XP Description
Barb All except for the stonefish who spawned it Barb.png 0 Spawns behind a stonefish using their active ability. Deals damage upon eating it (7% of max life). Poisons anyone who eats it with a base DPS of 10% that lasts 5 seconds (except poison-immune animals). Despawns after 4 seconds.
Bird Poop All except for lamprey and seagull Bird Poop.png 10 Affected by gravity. Automatically spawns below any seagull every 10 seconds.
Plankton All Food.png 25 Spawns in the ocean.
Dam Food Tier 1 to tier 7 Damfood.png 35 Spawns underneath beaver dams.
Ice All Ice.png 50 Spawns in the arctic and deeeep.
Algae Oarfish, penguin, tier 1 to tier 6 except lamprey Algae.png 50 Spawns on the ocean floor.

Volcano Food All except lamprey Lavabubble.png 125 Affected by gravity, floats upwards. Spawns out of volcanoes, which can be hidden in and are located in the arctic and the deeeep. When eaten as an animal that is not suited to the arctic, it will replenish some of your temperature.
Meat All Meat.png 1000 Spawns where an animal dies (tier 2 to tier 10 animals only). The amount of meat that spawns depends on what animal it was.
