of the go-kart track; the latter was demolished. Another new attraction is an carousel of the model Aviator. The new area opened in May 2008. In the Roxy 4D cinema, a film about SpongeBob SquarePants was replaced by Shrek, which again was replaced for the 2012 season by Ice Age. To this end, the Roxy 4D cinema was redesigned and a new preshow was installed. On 17 May 2010, Parques Reunidos bought the park from Palamon Capital Partners. No changes to the park's name or theming occurred. For the park's 15th birthday, on June 18, 2011, the combination of roller coaster and dark ride Van Helsing’s Factory was opened in the hall that formerly housed the Gremlins invasion and had only been used for Halloween since 2005. The roller coaster was built by the Gerstlauer company, the theme is based freely on the character of the vampire hunter Van Helsing from the 2004 film of the same name. According to the park, the roller coaster and the show "Shadows of Darkness", which uses the character of Van Helsing, are attractions that do not require a license. In addition to "Shadows of Darkness", which replaced the X-Men Show (ran in 2010 and 2011 in Studio 7), three more shows were revised for 2012. The novelty for 2017 was announced for the 20th anniversary of the park. It is a new roller coaster from Mack Rides and is called: Star Trek: Operation Enterprise. The track is located in a completely new themed area that is devoted to Star Trek. The themed area takes up the last parts of the former Marienhof, the former film museum and the unused space between the "Alien Encounter" and "The Lost Temple". The 40-meter-high launch coaster is the second tallest structure in the park and replaces the plans for the "Air Driver" roller coaster that were rejected in 2012. The following year it was announced that the Mystery River - one of the most popular and oldest attractions in the park - will be subject to a complete thematic redesign. The main changes are the waiting area, the theming and the effects during the journey. The ride will also receive a new soundtrack from IMAscore. The course of the journey itself remains largely unchanged. In 2019, the theming of Bermuda Triangle - Alien Encounter was slightly changed, the ride was renamed and a new soundtrack from IMAscore
