I remember the rainmaker and the sprinklers.
When I saw the guns in the Flooded Mine c.1995 (after a 13 year absence), I was confused and disappointed. Seemed like they didn't know what else to do with a ride that was a bit dated, so they just threw in a cheezy nod to pre-schoolers of the video generation. It was never a thrill ride (except the avalanche was a bit exciting), but I think it was more interesting back when you had to pay attention to the projected faces, signs on the walls, and the dialog.
