Frogger for the sega Genesis. 

In Frogger, the timeless arcade classic, the goal of the game is simple, to safely maneuver 5 frogs across five lanes of busy traffic, a fast moving river, three lanes of treacherous logs, two lanes of swimming turtles, while avoiding snakes, alligators and crocodiles. Sounds easy? You'll need lots of skill, and a bit of luck, as you hop to victory, while trying not to become a highway statistic by leaving your "mark" on the roadway!
