What is the name of Santa's ninth reindeer?

OLIVE. You know, "Olive, the other reindeer, used to laugh and call him names. They never let poor Rudolph, join in any reindeer games." Hee hee. That is one of my dad's old jokes. :)

So we'll call this little reindeer that Campbell is perched upon Olive. She fit on it just perfectly and could even hold herself up by leaning on the antlers!
