Five Nights at Sonic's 4: Halloween Edition

In this epilogue set decades into the future, the animatronic clones have undergone a complete transformation since their dark past, shedding their villainous nature to lead reformed lives. When they arrive to share their Halloween festivities with Luigi, their elaborate costumes trigger deep-seated trauma in the nervous plumber, who becomes convinced that his former tormentors have reverted to their murderous ways. As Luigi's fear spirals into nightmarish visions, the boundary between genuine threat and psychological terror becomes increasingly blurred, forcing him to confront whether the danger is real or born entirely from his own fractured mind.
