Plot
There was a school dance party in the nighttime at Flosyce Academy where the students were having fun playing games, eating food, and dancing. Sprucia and Gilli were making a lemonade stand in order to beat Ashley and Nadia opposing their smoothie specials, Prince Charles, Arthur, and the rest of the students tried their lemonade first. They became disgusted and appalled, they tried Ashley and Nadia's next. The students were evoked and attracted to the smoothies (including Gilli too). Without her sister's help, Sprucia walks to the garden to grab some for lemons and fruit to attempt beating the Olyvord sisters. Meanwhile, Madame Twilight invisibly appears at the party. She sees students drinking the strawberry smoothies, she then applies a sparkling virus in the smoothies (except Gilli's). When they tasted the embedded virus mixed with the smoothies, they start to feel dazed, sick, and ill. Everyone turned into turquoise yellow-spotted long-tongued zombies, slightly mind-controlled by Twilight. After when Ashley and Nadia were infected by them, they cornered Gilli and she gets licked too. Sprucia was on her way back to the party until she walks in and suddenly all zombies spotted her, she avoids them of their treacherous infectious tongue climbing on the roof but encountered an infectious Gilli pushing her out of the way inside the school using a window to a hidden room setting a barricade in the entrance to give the zombies more time to knock it down. Sprucia uses her vision power to find what caused the outbreak, she senses Twilight who caused the infected of the sprinkles she applied in the strawberry smoothies but not in their lemonade stand. Then she has an idea, Sprucia can go to the science lab to make a potion to turn the students back to normal. After making a cure, she applies it on Gilli as a test. Gilli turns back to normal, but is turned back into a zombie. Sprucia needs to make more cure, so she heads back to the lab. Professor Reuben was in the lab and Sprucia asks him to help cure the infected, she can use the disgusted lemonade juice her and Gilli made to mix it with the cure then use a pump to plan an attack. Reuben sets up the pump then Sprucia aims for the zombie's tongue, splashing them entirely. All students were turned back to normal and disgusted of the salty lemonade, Twilight attempts to escape but stopped by Sprucia, Twilight is arrested. Everyone and Reuben started having a party together.
