Raindeer names, the answer

Thank you for the both of you answering, you both came close but…Santa’s reindeers were called, Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen, and Rudolph, who eventually replaced the main reindeer, Olive. Olive was the main reindeer for Santa, but was a nasty, vindictive reindeer, who has been forgotten about since being replace by Rudolph. If in any doubt as to the truth of this tale, please sing the tune

Rudolph the red nosed reindeer,

Had a very shiny nose,

And if you saw it,

You would even say it glowed.

Olive the other reindeer,

Used to laugh and call him names,

They never let him join in any reindeer games.

That is a groaner lol
