BF and Pibby, still fleeing from the corruption, entered the Turners' home where they encountered Vicky, the torturous babysitter. However, she had succumbed to the Pibby Corruption, making her even more menacing than before. They engaged in a musical duel, with BF showcasing his impressive rap battling skills, but Vicky's intensity was overwhelming. Midway through the performance, Timmy appeared, also corrupted and grotesquely transformed due to the corruption, joining Vicky in her musical assault. The reason for Timmy's corruption was that he, along with his fairy godparents Cosmo and Wanda, had been unable to resist the Darkness. Timmy attempted to wish his fairy godparents out of the corruption's grasp or to eliminate it entirely, hoping to restore normalcy, but the Darkness was too swift, thwarting his wish and corrupting all three of them. Ultimately, Vicky became the first corrupted individual to triumph in a rap battle against BF, forcing him and Pibby to flee before she could corrupt them as well.
