Abstract: Various toys simulating animal characters have appendages with inserts therein which produce slow return motion of the appendages from positions to which they have been deformed to simulate a natural movement or gesture. The inserts each includes an elongate, tubular, resiliently compressible air bags with an impermeable (air tight), skin of plastic or rubber, penetrated by a slow leak valve formed as a small hole and stuffed with resiliently compressible synthetic fiber or foam. In one example the air bag is located in the body of a doll to extend across the chest and along respective arms, whereby a child can deform the arms between open and closed positions, compressing the air bag so that the resiliency returns the arms slowly to an undeformed position while producing a simulated natural gesture of affection such as giving or requesting a hug.
