A doll is provided. The doll includes a layer of skin formed from a first material to simulate human skin. The skin has an interior side and an exterior side. The doll also includes a chamber enclosed by the layer of skin with the interior side of the skin facing the chamber. The doll further includes a filler made of a second material, different from the first material. The filler fills the space within the chamber. The skin is formed by placing the melted first material in a first mold configured to have an inside contour resembling a human body or body part up to a certain level of the first mold and, when the melted first material solidifies, removing certain amount of the melted first material such that the remaining first material in the first mold forms the skin with a thickness in the first mold.
