Frogger Imitations

Freeway - One of Activision's first games for the Atari 2600, this game focuses less on why the chicken crossed the road, and more on how.

Ribbit - Is this a sequel or an imitation? On one hand, this arcade game was released by Sega, who originally distributed Frogger outside of Japan, and has an obvious link to that earlier game. On the other hand, original Frogger maker Konami had absolutely nothing to do with this game.
