Fish

This game was discovered in former Atari employee Mike Albaugh's personal folder on a backup tape from one of the old Atari Coin-Op Division's mainframes. It's unknown if it was ever supposed to be a real game or if the programmer was just having some fun in his spare time, but given how much work went into it it's probably the former. The game is only 4K which was considered small at the time (late 1983) when most games were 8K or even 16K in size. It's still not 100% certain if Mike Albaugh is the actual programmer of this game.
