The game is set in a pond with the player taking the role of a tadpole. The aim of the game is to build up a colony of frogs while avoiding the many hazards. The setting and characters are all quite true to life which was quite unique at the time. Most contemporary arcade games, even if not set in space, such as Frogger (with frogs that can't swim) and Centipede (which is basically a space shoot 'em up with characters that look like insects), were far from realistic. The instructions include descriptions of all the 'cast' including their Latin names and information not relevant to the game itself. Although it may appear to be an educational game it is actually a fast-paced arcade game.
