Five actors have joined the cast, including Disney Channel alums Corbin Bleu (High School Musical franchise), Meg Donnelly (Zombies franchise) and Jason Earles (Hannah Montana) in guest-starring roles, along with two series regulars: newcomer Adrian Lyles and Saylor Bell (Disney Channel’s I Didn’t Do It).

Created and executive produced by Tim Federle (Ferdinand, Better Nate Than Ever), Season 3 is set at Camp Shallow Lake, a family-owned sleepaway camp in California, as the Wildcats and their fellow campers stage a high-stakes production of Frozen and determine who is “best in snow.” In addition to music from the film, Season 3 of HSMTMTS will feature music from the Camp Rock and High School Musical franchises.
