The magma jellyfish is a species of jellyfish that appears in the Nintendo DS version of the video game SpongeBob's Atlantis SquarePantis. It is a jellyfish that stings the player with its hot surface and becomes larger when the player touches it. Due to this, it is extremely hard to destroy/defeat.
It is a magma-red jellyfish with five tentacles and many different shades of yellow, red, and orange. Its warm colors that look like fire are supposed to signify that it is dangerous to come in contact with.
Role in game
It appears at the diamond boss at the volcano of the Mu stage, with 15 in total to defeat (in every serve, four will come at a time, and at the last serve, three appear).
