Incredicoaster began life as California Screamin', but was re-themed on the Incredibles as part of the launch of the new Pixar Pier section of the park in 2018 and now includes enclosed tunnels. When it first opened it was the first American Disney coaster to go upside-down, this launched scream machine meant to resemble classic wooden roller coasters of yesteryear provides the greatest thrill at Disney California Adventure, and the longest roller coaster in the world with a loop.
