As the books describe them

He was quite short and stout and had a big head, which was flat at the top and supported by a thick neck full of wrinkles. But he had no arms at all, and, seeing this, the Scarecrow did not fear that so helpless a creature could prevent them from climbing the hill. The Wonderful Wizard of Oz, ch. 22
