I've heard that Darien Lake took the Barracuda Bay/'Cuda Falls slides down. The park's entrance is going to look so odd without the slides and not to mention the GP are going to be telling Darien Lake to get more water slides because of long line for Tornado, Big Kahuna, and Swirl City!
There's already a lot of space between 'Cuda Falls and Slingshot because there used to be more water slides behind 'Cuda Falls that were remove when Six Flags bought Darien Lake. Maybe at one point Six Flags had plans for a coaster to go behind 'Cuda Falls and later canceled the plans before they decided to put Slingshot in somewhere where old slides were.
