Duke & Peanut have a very, very well rounded and massive amount of knowledge and skills. Their personalities differ vastly--Duke is more of an artsy, creative fellow, and Peanut shines in computer programming and engineering. For obvious reasons, what one dabbles in the other must as well, and in doing so they've both got a good balance of both worlds.
Duke & Peanut are about 12" tall and 7" wide. They're made of fleece, felt, and love!
