Angela is planning on going trick or treating with her friends but can't risk wearing one of her mother's homemade costumes, so she orders an "Astro-Nutties" costume in the mail. On Halloween night, Angela decides to give Mark and Derek a scare. When the lights start flickering and strange, howling noises echo through Angela's garage, Angela wonders if her garage is really haunted or if it is just Mark and Derek playing usual tricks.
