John dorys are one of the fish ingame. Green john dorys are big in Peter levels, purple ones medium in Harry levels and small in Goliath levels. Like other different colored fish that are the same, they have no difference, but green ones are seen only in Peter and Harry levels and purple ones in Harry and Goliath levels.
- John Dorys are bigger than Harry The Pompano, which has the same size. This may be because they've grown.
- John Dories are playable in the original game, but not in the sequel.
