The Diamond Jellyfish is an extremely rare species of jellyfish that only appears in the DS version of the video game SpongeBob's Atlantis SquarePantis.
It is a jellyfish made of diamonds (by its name), and due to this, the player can't possibly defeat these jellyfish.
- It only appears as the diamond boss at the Reef of Mu stage, with four of them appearing on the stage.
- The player can't defeat the jellyfish since it is made of diamonds.
- Similar to the other DS jellyfish, they haven't appeared in any SpongeBob SquarePants episodes.
