This is the result of... sitting in church yesterday. Different designs for Santa's reindeer just kinda came out for fun, and I had my friend there to add her input (such as, "Comet should be really buff"). This may move to Scraps after a while, but then again, it may not... 'cuz I kinda like it.
Notes for likely pairs...
Dancer and Prancer: probably twins.
Cupid and Vixen: I would say they're husband and wife. They sound cute together.
Dasher and Blitzen: Not shown together but I think they'd be best friends. Like they'd go running (flying?) together and hang out.
