Goofy’s Sky School Roller coaster attraction in Paradise Gardens Park at Disney California Adventure, opened July 1, 2011, taking the place of Mulholland Madness. Inspired by the classic Goofy “How-to” shorts of the 1940s and 1950s, as well as the short Goofy’s Glider, this attraction takes novice pilots on a flying lesson through the wild, blue yonder.
