On January 5th, Puerto Rican children traditionally leave grass or hay at the foot of their bed or under the Christmas tree. This is known as "El Noche de Reyes" or "Three Kings' Night" and it is a Puerto Rican tradition that celebrates the biblical story of the Three Wise Men who brought gifts to baby Jesus on the night of January 5th.
