Donder is in charge of the reindeers eating habits.  He needs to make sure they all stay in shape.

Donder starts a training camp every year on Nov. 8 at which over 200 reindeer try out for a spot on Santa's team.

Last year Vixen got too heavy during the summer and almost lost her spot to a rookie.  But with hard work at training camp, she was able to keep her spot on Santa's team.

Donder runs a tough training camp.  Every day he has the reindeer lift weights for 2 hours, run 50 miles and do 500 push-ups.  Donder started this training camp back in 1961 because Comet and Cupid were so out of shape at the end of the summer that they couldnt pull Santa's sleigh and lost their spots that year to two other reindeer:  Ralph and Rodney.  No one knows about the swap so don't tell.
