This is the first time I purchase a doll that has its guts hanging out. I totally loved it. It is a great way that I am exposing my children to the human body. The inside parts do feel gooey. My 7 year old was weary of touching them at first. We had so much fun talking about the body parts. Next stop Museum of Science and Industry. They have a whole exhibit on animals and you can see the muscle and bone.
