Disney has released a new video featuring behind the scenes footage of Paradise Pier and the Goofy's Sky School rollercoaster at California Adventure. Paradise Pier has undergone a major transformation over the last two years, which has seen the addition of the World of Color nighttime show and the soon-to-debut The Little Mermaid: Ariel's Undersea Adventure dark ride. The reopening of the updated Goofy's Sky School on July 1 will mark the completion of the overhaul. Disney Imagineer Larry Nikolai offers an insight into the work being undetaken in the video, embedded below: [YOUTUBE]gGvOiiVnVuA?hd=1[/YOUTUBE] Goofy's Sky School is a revamped version of the former Mulholland Madness coaster, which closed on October 12, 2010. The attraction is a classic wild mouse coaster, featuring sharp turns and sudden drops and reaching a top speed of 27 miles per hour. The transformation will see it receive a new theme based on the 1940 cartoon Goofy's Glider, which tells the story of Goofy attempting to teach pilots how to fly.

In addition, the Corn Dog Castle will also reopen after a lengthy closure. These are to set to fit in with the new theme for the area, which is designed to evoke a 1920s-era seaside resort.
