First, the children leave their shoes under the Christmas tree on January 5th, and when they wake up in the morning, they find presents--money, candy, toys, etc.--in your shoes! Further down in Mexico, such as in Mexico City, the Kings take the place of Santa Claus. Santa just brings clothes. It's the Kings who bring you toys! When we first got married, Carolina informed me on January the 5th that she was leaving her shoes under the tree for los Reyes, and she expected something to be in them in the morning. I wished her good luck.
They also bake a little plastic baby Jesus into it that they call "Niño Jesus" (pronounced ninyo haysoos). Everyone eats a piece of the cake, hoping that they don't get the niño Jesus. If you get this plastic baby Jesus (in the picture below), it means that you are in charge of throwing a party and providing tamales for everyone on February 2nd. After eating one of these, you could quite literally say "I found Jesus in a piece of cake". (note: humor attempted here)
As much as I love my American heritage, I've come to a point in my life where I must admit that Mexicans are much better at enjoying holidays than we are.
