Fish
Fish are creatures in the Original Trilogy. They are red with white bellies and blue eyes and swim under the level in a circle with a 2-tile radius. They do not serve any purpose besides being ornamental.
Trivia
- In Wonderland Secret Worlds, there is a glitch where if the player watches the ending cutscene and replays a level with fish in it, any fish in the level will swim in the air. The fish can swim higher if the player watches the ending cutscene multiple times. This effect will be reset upon exiting and rebooting the game.[1]
