I designed this as a challenge when a friend said her son would freak if he got one! The limbs are made separately. The legs are then attached together with a few chain stitches between them for the crotch. Later on, the arms are attached, making a one-piece body. The head is continued upward from the neck. A bit of Tunisian colorwork is used for the front panel on the chest.
