- This article is about the enemies. For the collectible Bait items, see Jellyfish (bait).
Jellyfish are enemies found in water. They produce light, making them easy to spot in dark areas. After Hardmode is activated, Jellyfish are able to jump out of the water to attack players, often leaving them stranded on land. There are currently 5 Jellyfish variants.
- Jellyfish Statues can be Wired to spawn Blue Jellyfish.
- Green Jellyfish can inflict the Silenced debuff.
- Blood Jellys and Fungo Fish are immune to the Confused debuff.
- If knocked out of water and onto dry blocks, Jellyfish are rendered immobile until knocked back into water, or water reaches them again.
