On the enemy list, between ShadowMan and MagicMan are three blank entries.The third one is just a copy of the unused Fishy virus using a white dot as a sprite.
It's possible this was the intended second version since the first and the third one's HPs are 80 and 150 respectively. The third one is the same as the first, except with 100 HP. Its third variation, which cannot be encountered normally, is simply a clone of the first one. Not all enemies use them and, as a result, unused values exist. Every enemy in the game is given three slots for their variations, each one getting progressively stronger.
