Reindeer to my heart

Santa’s been around for centuries, but his annual flight around the world is so exhausting, the reindeer only last for one trip.
Most of them die soon after they land back at the North Pole Workshop. Those that survive aren’t in any shape to fly again.
So, Santa and the elves celebrate their success with a venison feast.
The next day, they look through the breeding program to determine the best candidates for sleigh duty, and they train them.
Eight reindeer make the cut, and after a few dry runs, Santa’s ready.
He cracks his whip, and they are off!
