The Ghost Jellyfish only appeared in the DS Version of Atlantis SquarePantis. It is a special specimen that appears only in the Jellyfish Shooter minigame and if the player does absolutely nothing without pausing, a Ghost Jellyfish will appear.
It does not have a ghostly look. Instead, it has a poison-green colour with crimson red spots.
- It is see-through by a little bit.
- The reason why it is ghost is that when it appears, it appears out of nowhere!
