I have no idea myself.
Or do I?
Yes, I DO have an idea. Using fantasy creatures allows for more action, for it is less believable for a human to move a lot; we generally tend to sit and talk IRL. I hope it does make sense.
Also, it looks like it is based on a book from the 1920's. By the same guy who wrote Night on the Galactic Railroad. And the film directed BY THE SAME GUY WHO ADAPTED THE LATTER BOOK INTO ANIMATION.
Talk about coincidences!
