Billy is an unusual baby--he was born with a mustache And his pal Javier was born with a beard. Things get even sillier on Christmas Eve when Javier's beard turns white and he becomes Santa Baby Being Santa Baby is a lot of work--listening to the other babies' Christmas wishes, taste testing treats, and getting the dachshunds, ahem, reindeer, ready for their big night. Luckily, Mustache Baby, AKA Elf Baby, shows up in the St. Nick of time to help make the toys. But when he finishes, he decides to keep them all for himself Hijinks ensue, landing Mustache Baby firmly on the naughty list. That is until a visit from Santa Grownup reminds him that it is much more fun to give than to receive. The perfect holiday gift for any family with a mustachioed or bearded dad.
