Jellyfish are enemies which appear in underwater levels in Crash Bandicoot: The Wrath of Cortex and Crash Bandicoot: The Huge Adventure.

Crash Bandicoot: The Wrath of Cortex

Crash must avoid them or he will be electrocuted. They can only be destroyed by missiles from the submarine or by Aku Aku invincibility, as they can also shock Crash from far distances. They will continuously file out of pits in the ground. Crash must either quickly maneuver past them, or blast a hole through the line of jellyfish and move through.

Crash Bandicoot: The Huge Adventure

They reappear in this game. Unlike before, they can be defeated by Crash's spin.
