Abstract
A doll is provided capable of blowing bubbles. The doll has a receptacle for holding bubble making liquid attached to the doll's trunk. A bubble making tool having a ring-shaped end is attached to a moveable arm of the doll. The arm is able to pivot about the trunk so that the tool may be dipped in the liquid and raised up to a mouth opening formed in the doll. An air impeller is located in the doll's head and forces air out of the doll's mouth when a circuit is closed by the motion of the arm in bringing the tool close to the mouth opening. Bubbles are produced when the air flows through the ring-shaped end of the tool coated with a liquid film.
