Taking a firm stance against bipedalism

James continues to be the world expert in cruising along the coffee table, holding on only by a finger or two. He has absolutely no interest in losing the coffee table, though. This is in part because he's learned to crawl three-legged, so that he can carry something undamaged in one of his hands. Once you can move and carry your snack around, he's obviously reasoned, who needs to walk?

This also has the advantage of making him somewhat less of a flight risk.
