Ducks Ahoy!

Ducks Ahoy! is an arcade-style game for the Atari 8-bit family of computers and the Commodore 64. In it, the player maneuvers a boat around a flooded city to pick up ducks and ferry them to safety before they drown. The player must also avoid a hippopotamus, who randomly appears to try to destroy the player's boat. It was released in 1984 by CBS Software.
