Mouse Motel: Rooms go fast in these cozy, critter-filled pumpkins, which offer a shudder-inspiring alternative to traditional carving motifs. 1. Using a marker, draw a circle for each hole. 2. Cut out holes with a keyhole saw; shave edges smooth with a scraper if desired (no interior scraping is required). 3. Fill holes with rubber mice (available at Halloween stores). 4. Listen for screaming neighbors.
