Disney+ just unveiled the trailer for season 3 of High School Musical: The Musical: The Series.

The new season will premiere on July 27 and will feature newly-announced guest stars Jesse Tyler Ferguson and JoJo Siwa.

With a high-stakes production of Frozen on the horizon AND a drama-filled ‘docu-series’ of the production in the works, the Wildcats will attempt to show who is ‘best in snow’ without leaving anyone out in the cold.”

Ferguson will play Marvin, an old family friend of Olivia Rodrigo’s character Nini. Siwa will play Madison, a Camp Shallow Lake alum.
