Giant Jellyfish are large, aquatic predators exclusive to ✔️DLCDownpour. They are found in large bodies of water, either swimming up and down underwater or staying immobile at the surface. They use their tentacles to grab onto prey and drag them in to deliver a lethal electric shock.


Giant Jellyfish are large aquatic creatures that have some similarities to their smaller namesake, the Jellyfish. They have a round body surrounded by a disc-shaped mantle, numerous tentacles of varying length and shape, and a large, circular electrical organ suspended underneath them that emits orange light. Their pale skin ranges in color from dull pink to an albino-like white. Their shorter tentacles appear as a chain of several rings, while their longer tentacles are thin tendrils. If underwater, their mantle expands and contracts slowly as a means of propulsion.



It is fairly easy to kill Giant Jellyfish floating at the water's surface using Spears, since only 3 Spear hits are required to kill a Giant Jellyfish as Survivor. This can be done safely outside the Giant Jellyfish's reach using multiple Spears or up close with a single Spear. To avoid the Giant Jellyfish's tendrils up close, it can be helpful to jump out of the water and stand on top of their body, though it is easy to slip off as the surface is round and frictionless.


Giant Jellyfish detect prey through vibrations in the water around them, most often from entering or exiting the water. They are also capable of hearing sounds originating from out of the water and are easily distracted. If distracted by other sounds from above the surface of the water, Slugcat can swim below the reach of their tentacles. If their tentacles are dangling beneath the water's surface, it may be better to quietly swim over the surface of the water and try to climb over top of it.


Giant Jellyfish have difficulty capturing prey at the surface of the water. The grasp of their tentacles can be shaken off by jumping out of the water, and the top of their body is not electrified, so Slugcat may skim the surface of the water and climb over them. Alternatively, they can be avoided by diving underneath to avoid their tentacles. Avoid getting too close to the middle where the tendrils have an easier time ensnaring prey. Slugcat can also grab a Jetfish to easily move past them or use the Jetfish as bait to distract them.

Abilities & Behavior

A Giant Jellyfish swimming and eating a dead Jetfish.

The Giant Jellyfish delivers a strong electric shock to any creature that comes in contact with the bulb below their head. Giant Jellyfish at the water's surface are stationary, while Giant Jellyfish fully submerged in water swim up and down.

Once the Giant Jellyfish detects prey, they move their tendrils towards the creature in an attempt to grab them. If successful, they bring the creature closer to their center to shock and consume them.

If a Giant Jellyfish is displaced from their original position, they quickly move back to their previous spot.

A Giant Jellyfish may, rarely, deliver a nonlethal shock through their grasping tentacles.

When near a Giant Jellyfish, they make a deep, booming noise.

Upon death, Giant Jellyfish burst into a pile of white blobs and 3-4 Slime Mold from the orange glowing sack under their body.

  • The noise the Giant Jellyfish makes is called a 'Moo' in Safari Mode controls.
  • Removing a Giant Jellyfish from their body of water results in them exploding and dying immediately. This can be achieved with the devtool cursor or by attempting to spawn one on land in Arena mode.
  • Giant Jellyfish are classified as objects in the game's code, similarly to Stowaways.
