help me remember few sega game names

one is where you controll a penguin and you have to avoid tigers and gather little chickens or something like that.

other is some kinda western game , there was 2 characters 1 with shotgun (mexican with sombrero) other one with normal pistol , cant remember anything more :(

Second one = Sunset Riders?

yea i think the second one is sunset riders. , sunset riders is one of my favrot games on the sega

First one has to be Flicky, I can't think of any other game that's like what you described. Second is definitely Sunset Riders, awesome game.
