This, of course, leads to Boopkins dumping her, and her going insane, plotting revenge on him and the main protagonists. In her debut episode in the SMG4 universe, she comes to life when Fishy Boopkins uses Kamek's wand to make her come out of his dating sim, Kevin's School, but in real life, she becomes extremely jealous, destroying anything that might get between her and Boopkins, even his waifu body pillows, which she ignites with fire.
