Road Runner Rollercoaster, a Vekoma Junior model, opened on Boxing Day 2000; it was Australia's first coaster designed for children. During 2001, the Great Gremlins and Gravity Homestead attractions closed, and the Looney Tunes Splash Zone was added to Looney Tunes Village. Two new attractions opened on Boxing Day: Batman Adventure – The Ride 2, a refurbishment of the original, and the Harry Potter Movie Magic Experience. Built on the Gravity Homestead's footprint, the $2 million Harry Potter attraction was a direct tie-in to the film series' first film, "The Philosopher's Stone", and featured a walk-through replica of Diagon Alley and a live owl show. The following year, it was updated with the release of "The Chamber of Secrets" to feature film set pieces such as the flying car and creatures of the Forbidden Forest. Scooby-Doo Spooky Coaster opened on 17 June 2002; the $13 million Wild Mouse coaster by Mack Rides was themed to the 2002 film "Scooby-Doo". The indoor ride featured ghost train elements, an elevator lift and a coaster section.
