Well, maybe I should say something like spinning ufo ride or flying saucer ride, lol, and I guess Planet Coaster was never meant to be a direct upgrade of RCT3. It is a different game, and separate from the RCT series which Atari now owns, it may have some rides that were in RCT3, but it also has rides that weren't officially in RCT3. The game was probably never coded to allow water park attractions and peeps swimming.
