Odell Down Under is a game for the PC and Macintosh that takes place in the Great Barrier Reef. You take on the role of a fish who must eat, stay clean and avoid being eaten by predators to survive. You can make your own fish and in campaign mode you keep on growing in every level you pass until you reach the top of the food chain, starting as a silver sprat and becoming the great white shark. Some special fish have special moves; for example, the stingray can sting attackers, and the squid can squirt ink. Currently out of production, this game is very difficult to come by.

Other playable species include the flashlight fish, moray eel, Achilles tang, and blacktip shark.
