Previously called Ben 10 it opened just in time for the 2011 Easter weekend.
Accelerator was the first Vekoma Junior Boomerang rollercoaster in the world, adapting the well-established Boomerang design to suit a younger audience. While it does not feature any inversions, it retains the basic "out-and-back" layout that inspired the Boomerang's name.

The ride features a 65-feet-tall first lift hill, which the train is pulled up in reverse. It then traverses the circuit once in a forwards direction, before completing a return facing backwards. The relatively short 590 feet (180 metre) circuit features one large banked turn and a helix, with the coaster hitting a maximum speed of 34 miles per hour.
