Aqua Man

Akuaman (アクアマン, translated as "Aqua Man") are enemies from the game Donkey Kong on the Game Boy. They resemble short humanoid creatures wearing diving dress. They first appear in Stage 3-3 on the Ship. Akuaman only walk around horizontally, changing direction once they encounter a platform's bounds or a wall, and if Mario runs into them, he will lose a life. He can hop on them and hitch a ride as the creatures stroll. To defeat an Akuaman, it has to be heaved and thrown at another enemy; altnernatively, it can be crushed with a Hammer.
