Let me sum up:
The lonely, blue centaurs finally get some play...
Let me splain:
Sometimes, when you're a lady centaur, and you don't get quite as whored-up as the other lady centaurs, it takes you a while to find a nice boy.
Happy Valentine's Day!
P.S. Incidentally, the centaur scenes originally included a small, black centaur polishing the ladies' hooves and weaving flowers into their tails. In the later 60's re-release, Disney had enough sense to artfully zoom in on the hot, pale centaurs for these scenes, but for a while actually denied that the decidedly un-PC character had ever existed. Oh, Disney.
