In 2003, Wildwater Kingdom was overhauled. Several older body slides were removed and replaced with four modern colored body slides, two of which were open and two of which were enclosed tube slides. Three inflated tube slides were also added. One of the slides is mostly open and straight down, another is winding and completely enclosed, and the third slide also winds but is partially open. A new children's water play area was also added. In July, the park announced that Hercules would close Labor Day and in 2005 be replaced by Hydra the Revenge, a $13 million, steel floorless Bolliger & Mabillard coaster. Hercules closed and would be replaced as a result of high maintenance costs, a rough ride, and low ridership. Soon after, it was demolished, reducing the coaster count to eight.
