In April 9th, Arthur and his friends from Lakewood were transferred to this school while Lakewood was under repairs from being destroyed in a fire, but eventually transferred back to Lakewood when it was restored, since they never got along with the kids at Mighty Mountain. Binky and his friends, the Tough Customers, used to go to this school before transferring to Lakewood Elementary.
