Artistic license

Check out Baby Jesus. 
Pretty hefty for a newborn. 
Quite a head of hair for a newborn. 
Strangest of all, he's blond!

Now take a look at the animals.
A rather weird assortment.
What is that creature with the horns? 
Not a cow, not a bull .... Maybe another virgin?
And I don't recall a dog in Bethlehem.

Not my favorite crèche.
