I've debated endlessly on whether it's pronounced "Crescendoll" or "Crescendolls". I'm sure I've used both in the comic and various description. In the long run, I've realized that I am over-analyzing a goddamn name and decided either is acceptable.
Oh, and that last page is the last scene with the ponies. They're done. It's over. MLP: Friendship is Magic fans, you can return to your daily lives and ignore me now.
