On July 8, 2015, Adventureland announced that they were adding a new roller coaster called The Monster, a Gerstlauer Infinity coaster and the first of its kind in the United States. It opened to the public on June 4, 2016 after park employee previews a few days earlier. It replaced the River Rapids log ride, which ran since the park first opened. The Monster features a unique nighttime LED light display made up of 137 track mounted fixtures that synchronize to the ride vehicles, and 46 ground lights.
