Old Macintosh Performa game

Hello everybody! First time- long time on these forums. I am trying to find this old Macintosh game I had when I was a really young child. It was with 2D sprites, and you’d click and drag out different characters onto a still background. These characters would animate and move across the screen left to right and right to left. There was a dinosaur level where you’d drag out t-Rex’s and cave men. The T-Rex would eat people. And there was a Wild West level where you’d drag out gunslingers and one went “Yeeeha” every time you clicked on him. And there was a space level where you were on the moon. Anyone have any ideas?
