Sharpay Evans (Ashley Tisdale) performs a dance number at the Lava Springs Country Club ("Gonna Shine").

There, she meets famous producer and casting director Jerry Taylor (Pat Mastroianni), who offers her a chance to star in his newest show on Broadway.

He hesitantly accepts, but he has a condition; if the plan backfires and she is not in a show by the end of the month, Sharpay will need to move back with her parents and work at Lava Springs.

While moping on the street, she meets Peyton Leverett (Austin Butler), an aspiring film director and son of Sharpay's mother's friend from college.

She becomes discouraged, but with the help of Peyton, she auditions him ("My Boi and Me"), only to be caught in a tie with the very competitive child star Roger Elliston (Bradley Steven Perry) and his pedigree Cavalier King Charles Spaniel, Countess ("My Girl and Me").

Rehearsals begin the next morning with the directors Gill Samms (Alec Mapa) and Neal Roberts (Jack Plotnick) using both dogs interchangeably to determine which one will get the role.

Her plan works when Amber Lee reveals her true colors to the audience, who become outraged and begin booing her, with her outburst.

In a scene exclusive to television and Netflix showings, Sharpay's twin brother, Ryan (Lucas Grabeel), on a break from his musical tour around the country, pays her a visit after she becomes a star on Broadway to congratulate her.

When Boi escapes from Sharpay's apartment, she chases after him, and Ryan relaxes on his sister's bed until it folds back into the closet, taking him with it.

In making the announcement, Gary Marsh, the president of Disney Channels Worldwide, said: "In 'Sharpay,' Ashley Tisdale brought to life one of the most memorable comedic characters we've seen in years.

[8] Former High School Musical actress Vanessa Hudgens expressed interest in making a cameo appearance in the film.

[11] Songwriter Amy Powers stated on her official website that Tisdale had recorded the songs "My Boi and Me" and "The Rest of My Life" (both were co-written with Matthew Tishler) for the film.

Brian Orndorf stated "Though frivolous, Sharpay's Fabulous Adventure is an enjoyable romp with everyone's favorite pampered princess, delivering limited antics with a great deal of charisma.

"[20] David Nusair of Reel Film Reviews called it "...bland and surprisingly low-rent..."[21] James Plath said "Though Sharpay's Fabulous Adventure doesn't have the same verve or originality of the 'HSM' movies, it's still solid-pink entertainment that should delight the target audience of mostly pre-teen and early teenage girls (and boys who like Tisdale but would never, in a million years, admit it).
