Abstract
A stuffed toy with a heater is disclosed, which comprises a cover configured to resemble a predetermined object and a latent heat storage material disposed in the stuffing in the cover. When the latent heat storage material is heated it undergoes a transition from the solid phase to the liquid phase and stores a heat of dissolution. When it undergoes transition from the liquid phase to the solid phase, it gives off heat so as to maintain the temperature of the toy relatively constant for long periods of time.
