Olive, the Other Reindeer

Olive the other reindeer
Was a little tiny dog
She helped Mr. Santa make it through
the North Pole fog
She flew down on a piece of string
Comet put her there
And when the gumdrops began to fall
She helped Santa get them all
Now all the other reindeer
Have a new doggie friend
Her name is Olive
And now the song must end
