January 6th is the epiphany and it is celebrated with a cake called the "galette des rois" or "King's Cake" which celebrates the three wise men visiting the Baby Jesus. I'm pretty sure that it's actually just an excuse to continue the holiday season. The "galette du rois" are brought in all through the first weeks of January to work places and immediately crush hopes of keeping new year's resolutions to eat better.
Despite the two cakes that were doled out, only one figurine or "feve" was found inside. Perhaps the other one ended up in someone's tummy?
