Home of the Ancients

When Grim misuses his powers to play bowling with asteroids, he is taken to the Underworld court and sentenced to 50 hours of community service. At a retirement home, Billy, Mandy, and Grim go to the supernatural wing, which is the Home of the Ancients, a place for retired, geriatric monsters. Grim meets his childhood idols, the Bride of Frankenstein, Dracula, and the Wolf Man. Despite Billy's comments that the old monsters are finished, Grim sets out to prove that they are still scary. Grim tries to scare a bunch of kids in the woods, but the old monsters ruin his attempt and he walks out on them.
