Shamus Culhane changed Woody considerably, as well as giving Woody his iconic redesign. His take on Woody was much more fleshed out than the previous incarnation — wheras the original character was just a mindless heckler that went about causing havoc on sheer principle, Shamus supplied Woody with more clearly defined traits so that we could understand why he was going about causing trouble — specifically, by estasblishing that he is a selfish, ignorant being who only stands for himself and will not stop at nothing to achieve his goals, regardless of whoever gets in his way. He also helped firmly establish Woody's trait of being a big food enthusiast (which did pop up in early cartoons, but wasn't a central part of the character) which served as the basis for many of his cartoons. However, Culhane's direction, for all of his improvements, made Woody a bit too unlikable, taking him from being a screwy bird to sometimes being flat out malacious in some episodes (i.e. The Barber of Seville).
