Pibby has journeyed across the universe with BF to rescue survivors. Upon arriving in Gumball's world, she was met with overwhelming corruption. She found herself in the Void, a surreal space where everything floated, a result of the corruption's spread or the show's cancellation after The Inquisition. Suddenly, Gumball appeared, covered in corruption, with some oozing from his mouth and others clinging to his head. Pibby knew she had to confront this once joyful cat and escape with Darwin, his loyal companion. Meanwhile, BF was nowhere to be found, as he was busy searching for survivors in various universes under siege by the Pibby corruption, aiming to bring them to safety and help them recover from the devastation.
