The trailer for High School Musical: The Musical: The Series Season 3 came out this week, and while we were prepared for all of the hype around Camp Shallow Lake, we were not prepared for some other exciting reveals including some special guest star moments we are on the edge of our seats over.

HSMTMTS Season 3 takes our Wildcats to summer camp for two weeks, but of course Camp Shallow Lake isn’t all team building and s’mores. There’s a performance on the way. The cast will be the first camp to put on a camp production of Frozen, and while the campers are dealing with personal drama and being separated from their cellphones, they’ll also be vying for the best roles.

Along with sneak peeks at romance, hilarious bunkmates, and summer camp celebrations, we also got two exciting guest star announcements. Original Wildcat in the High School Musical movie series Corbin Bleu will be appearing in Season 3 as himself and directing the camp production of Frozen. JoJo Siwa also appears in the trailer, and while she is wearing a very JoJo outfit, according to Entertainment Weekly, the pop star and SYTYCD judge will be taking on the character Madison a former Camp Shallow Lake camper.

High School Musical: The Musical: The Series Season 3 stars Joshua Bassett (“Ricky”), Sofia Wylie (“Gina”), Matt Cornett (“E.J.”), Julia Lester (“Ashlyn”), Dara Reneé (“Kourtney”), Frankie Rodriguez (“Carlos”), Saylor Bell Curda (“Maddox”) and Adrian Lyles (“Jet”). Also featured this season are guest stars Aria Brooks (“Alex”), Liamani Segura (“Emmy”) and Ben Stillwell (“Channing”) as well as guest stars Corbin Bleu (himself), Meg Donnelly (“Val”), Jason Earles (“Dewey Wood”), Kate Reinders (“Miss Jenn”), Olivia Rose Keegan (“Lily”) and Olivia Rodrigo (“Nini”), Larry Saperstein (“Big Red”), and Joe Serafini (“Seb”).

Also joining in on the summertime fun are Disney and TV favorites Jason Earles, Jesse Tyler Ferguson, and Meg Donnelly.

High School Musical: The Musical: The Series officially heads to Camp Shallow Lake on Disney+ on July 27. Grab your sleeping bags and your bug spray (and maybe put your phone in a bucket?). It’s summertime!
