They are indeed from my world, and no, I've no idea how they came to be here. They had simply manifested when I woke up this morning.

Ah - no, that would be the rooster. Well, not wings, but levitation, at any rate. [ He floats a bit higher to illustrate. ] The other animals? Oh, let's see here. Ox is strength, rabbit is speed, snake is invisibility, horse is healing, dog is immortality... sheep is astral projection, bloody useless power... what else?
