When Radio KBLOOD announces a contest of which the prize is that the Jaundice Brothers come play at the winner's school's homecoming dance, Cleo helps Frankie put together a tape to sent in. As luck has it, they win the contest. Cleo participates in Monster High's 1361st Annual Charity Talon Show. One of her competitors is Clawdeen, who takes the stage just after her. Cleo attempts to sabotage Clawdeen's performance by turning on the spotlight, which works as a substitute full moon on her. She loses control, but rather than it being disastrous, she improvises her way through a killer dance that easily beats Cleo's.  Cleo's Trigular Calcometry 101 class is hosted by a substitute teacher, Lou Zarr, who does not get along with the class. A conflict with Deuce leaves him petrified, upon which Cleo and the other students consider the class dismissed. When Clawdeen shows up unprepared for the SAT that day, Cleo advises her to copy Ghoulia's answers.
