Jellyfish

Jellyfish are enemies found in water. They produce light, making them easy to spot in dark areas. Jellyfish are able to jump out of the water to attack players, often leaving them stranded on land. In Expert Mode Jellyfish will periodically become electrified, making them invincible for the duration of the attack. There are currently 5 Jellyfish variants, 3 of which only appear during Hardmode.
