The student bodies are in for a jolting surprise when Frankie pieces together an energy smoothie stand.
A party is held at Monster High and Frankie helps out with catering, creating and distributing smoothies to her fellow students and the teachers present. All of her acquaintances are vocally enthusiastic about her blends, which draws the attention of Toralei, Meowlody, and Purrsephone. Almost immediately, Toralei hatches a plan to bully Frankie.
Approaching the stand, Toralei pretends she wants a smoothie too, but her true purpose is to reject each one Frankie offers her, thereby stressing Frankie and holding up the line. Frankie remains oblivious of the werecats' prank, even if the line grows and starts complaining, but she does become frustrated over Toralei's minute complaints. Along with her bad mood, her charge increases, until by accident she electrifies a new smoothie she'd been working on. Toralei grabs it and ignores Frankie's warning not to drink it. Part of the charge passes on to her, which worries Frankie at first, but then Toralei states that though she wants to hate the drink, she can't. She throws it to Purrsephone and makes her way to the dance floor. Taking a sip themselves, Purrsephone and Meowlody soon join her, prompting the other students and even Headless Headmistress Bloodgood to want an electrified smoothie too.
Before long, everyone is dancing to Holt Hyde's music. With no one to serve anymore, Frankie cleans up, happy with the energy her smoothies injected into the party.
