Though Halloween has usually been seen as an American influence in the Philippines, the country's trick-or-treat traditions during Undas (from the Spanish "Honras", meaning honours, as in "with honors") are actually much older. This tradition was derived from the pre-colonial tradition called pangangaluwa. Pangangaluluwa (from "kaluluwa" or spirit double) was a practice of early Filipinos who sang from house to house swathed in blankets pretending to be ghosts of ancestors. If the owner of the house failed to give biko or rice cakes to the "nangangaluluwa", the "spirits" would play tricks (try to steal slippers or other objects left outside the house by members of the family or run off with the owner's chickens). Pangangaluluwa practices are still seen in rural areas.
