Ribbit!
The Game: Two frogs, Bull and Pip, set out on a hazardous journey…to find some flies to eat. They must grab yummy flies while avoiding several lanes of poisonous spider “traffic”, and they also have to cross the occasional river on 
the backs of turtles and logs, snatching more flies out of the air without falling into the water. Each screen is cleared by the frogs eating the required number of flies. (Sega, 1991)
Memories: It’s not Frogger. It’s not even officially a sequel to Frogger (by this time, Konami, the originators of that game, had reasserted their ownership rights). But I’ll be croaked if Ribbit! isn’t at least “inspired by” Frogger - how that one didn’t get the lawyers suited up for an amphibious mission, we may never know. (Read more about this game…)
