The magma jellyfish is a species of jellyfish that appear in the DS version of the video game SpongeBob's Atlantis SquarePantis. It is a jellyfish that stings the player with its surface and becomes larger as the player touches it. Due to this, it is extremely hard to destroy/defeat.
It is a magma-red jellyfish with 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 (in every serve, four will come at a time, and at the last serve, three appear).
