Anything is possible except where impossible by the laws the world work by, and even then something from another world crossing over can make that thing possible. Such 'blending' incidents are one of the things we work to deal with here.

I not only know the creator of my world personally, I watched her create it. And the only limits in worlds of dreams are the imagination. If you dream it, raccoon dogs will become nyuudo and anything will shapeshift. And to me, those things are reality, because I am an entity born of dreams.

I've learned that many other worlds work differently, but I still have many things to learn.
