Promenade

Fright Knight School is a 22-minute flash-animated comedy streaming special of the Knight School franchise, which premiered on HBO Max on Thursday, May 18, 2028. With Anna Kendrick and Avril Lavigne busy with the Knight School prequel Yeoll High while chosen cast members reprise their roles from the films, Chelsea Kane returns as Ellenor from Fright Knight School while AJ Michalka replaces Lavigne as Darcey after last voicing her in Back to Knight School.

In Promenade, the story focuses on Darcey preparing for her prom and to live out the climax of her favorite movie with help from Ellenor.

Plot
The end of the school year was approaching, which meant prom was coming, and Darcey had been waiting for prom so she could live out the climax of her favorite movie School Dance. Since she had already asked out a student to prom, all she had to do was plan out her night. Her memory of School Dance was blank, so she had to watch it again to use its plot-points for her dance with her date, only for her to get lost in the story; she calls up Ellenor for help. As Ellenor was neutral on its concept and premise, as well as Darcey's ridiculous goal, she was willing to help her best friend out regardless. She prepared her for the night by writing down the details from the movie to buying her a dress that the protagonist wore for "good measure", following Darcey's plan on re-enacting the movie to a 'T'.

Meanwhile, Bill was searching for a date to prom, with little results. The former Knight School students, while Andrew was reluctant, even help him out, but end up getting their own dates from backfiring or failing results. Lance gives him advice in asking out girls such as being himself and showing helpfulness, which results in girls getting weirded out from his normal self and showing ungratefulness in his help. In another attempt, they find a group of girls at the local park and Bill does an attempt to ask one of them out, with one agreeing to go with him. Elated, Bill goes home to get ready

As Yeoll High's "Prom Nite" had come, Darcey arrives with the boys as her entourage and waits on her date Chuck, only to discover that he had asked out a different girl to prom; Darcey, heartbroken, shoves him to the floor and runs out. Ellenor finds her in the girls' bathroom bawling over how she was stood up, with Darcey adding how disappointed she was not to dance with an attractive boy; Ellenor gives her a reality check and makes it up to her by setting her up with Bill, who could not bring his date as she was not a student. As it was time to dance, Darcey and Bill dance together while conversing about School Dance (which Bill also adores) to where they discover they have a few things in common. Ellenor and Lance are grateful for each of their friends hitting it off with each other while sharing their own dance. Andrew changes the slow dance music to the dance-pop song "I Gotta Feeling", resulting in the students dancing their own ways while Darcey and Bill resume slow dancing together. As Whitey was about to change it back, Mr. Begley, who took occupation after Knight School was renovated, stops him and lets the students enjoy the night.

Development
After production on Fright Knight School, franchise creator Xavier Shaquille had planned making a third special for HBO Max that focused on Darcey. As there were returning cast members from the films and specials, Shaquille had brought AJ Michalka in to voice Darcey; marking this the first special where Avril Lavigne does not voice Darcey as Lavigne was voicing her in the prequel Yeoll High. Chelsea Kane was already cast as Ellenor as Anna Kendrick was voicing her in Yeoll High as well.

Music
Mark Mothersbaugh returns to compose the special after Fright Knight School.

"I Gotta Feeling" by The Black Eyed Peas was used in the special in a few scenes; in its first scene where Ellenor and Darcey get ready for prom, it was played alongside Kidz Bop's cover to showcase distinction in Ellenor and Darcey's traits and personality; The Black Eyed Peas' version plays for Ellenor as she is mature and desensitized while the Kidz Bop cover plays for Darcey as she is childish and immature. "I Gotta Feeling" plays again in the very end when Andrew changes the slow dance music.
