Yeah They Made some good cave men games for Snes but please , Stay away from Chuck rock and Super bonk!! Chuck Rock just sucks and Super Bonk is just plain wierd.
^^^ Super Bonk is an awesome game. I love it; even though some of his transformations are kinda strange.
I think you are thinking of Congo's Caper! Am I right?
If so, I own it. I love that game, very fun to play :D
Also, it's one of the more rare ones to find on the SNES.
