There are trainers that can enable the "mountain tool"; without trainers, it's only available in the scenario editor. As far as I know, the only "booster" of any sort left is the Steel Twister's launched lift hill. As for getting pink water in a scenario, I suppose you could load the scenario back into the scenario editor, put in the pink water, and save it as something else; however, if you do that, all rides and attractions are removed from the scenario when you load it into the scenario editor.
