The Rolling Rock is a limited-time premium decoration released on May 5, 2015 during act 2 of the Terwilligers 2015 Event.
Rolling Rock is a tourist attraction in Shelbyville. It was visited by Selma and her husband Sideshow Bob. While filming her trip Selma mentions the various attractions and briefly films the rock, which is continually rolling in a halfpipe.
- The rock as depicted could not occur naturally, as it would quickly lose momentum to friction and roll to a halt.
