Halloween is celebrated on October 31st and involves dressing up in costumes. Common costumes include witches, ghosts, vampires, aliens, devils, mummies and skeletons. On Halloween, children go door-to-door saying "Treat or treat" and receive candy. The story describes an old man who carves a large pumpkin named Old Jack and lights it on his porch, attracting many happy children who receive candy. Ever since, Old Jack has saved the man from lonely Halloweens.
