Basically, when Kali was being designed they had a lot longer path and more show effects and incorporating the gibbons and siamangs and tigers. But of course, after budget cuts, they got the bare minimum. When they bought the ride from Intamin, they just got the bare minimum to run the ride with no options but there were plenty of options that would make the ride easier to operate also. It was just like buying a car with plenty of options like power windows and power locks and a/c or you can get a bare bones version with roll up windows and manual locks and no radio or a/c. The only thing Disney added to the ride was the boat stops at the top of the downramp and at the entrance to the turntable and a handicap loading area.
The show effects were all built by Disney and tried to go the cheapest route possible and we were instructed not to get people wet with the show effects, the 3 geysers at the top of the upramp, the leaking pipe, the leaking cave, and the tri-jets. With the tri-jets, we tried to aim them at the rafts but they wanted them above the rafts for people wouldn't get wet just make them think that they would get wet. The only show effect that was designed to get people wet was the Elephant Gag because were orginally go to pay to operate that, but then decided not to be coin operated because that would cause problems also with someone trying to fix them all the time.
