When it comes to understanding the inner workings of the human body, touchable 3-D body parts are the best. Especially when they are of a cheerful, baby-sized boy doll whose torso can be zipped open to reveal all relevant organs: heart, lung, liver, kidneys, bladder, spleen as well as the digestive system. All of Erwin’s organs are made of super-soft plush and can be removed and reaffixed with the help of color coded Velcro patches. He comes with a hospital gown and an instructive manual.
