Whats happened to Rump?

This pic is from Bobby's Twitter page. Any takers want to spit out their theory as to why hr looks like this.

My theory is that he is changing back into his beastly self because he is in a place with more magic than Storybrooke. And that is why when he was on the Jolly Roger he changed his wardrobe and why he dropped his cane because when he is the Dark One he doesn't need it.

Let us hear what you think
