This is my interpretation of a Billy-Bumbler. Kinda what I visioned when reading Stephen King's Dark Tower (c).
It's not Oy (from the book), it's kinda like my own one. He's ment to have a long slender body, but it's kinda hard to tell, as he's scrunched up, washing his back. His tail is coiled up tightly againsed him also. He's chubby for a Billy-Bumbler, guess I fed him too much. ^_^;
