Doll with simulated bowel movement

DETAILED DESCRIPTION The invention features a toy doll that is capable of exhibiting a simulated bowel movement.
When a feeding bottle is inserted into the doll's mouth, the simulated bowel movement is extended from an opening in the doll's torso.
Wiping the bowel movement toward the rear of the torso causes the bowel movement to be retracted into the opening.
The simulated bowel movement promises to add to a child's enjoyment when playing with the doll.
In one aspect, generally, the invention features a doll having a torso with an opening.
The doll also includes a simulated bowel movement configured to be moved through the opening between positions respectively inside and outside the torso.
Embodiments of the invention may include one or more of the following features.
The doll may have a drive mechanism configured to drive the simulated bowel movement through the opening in response to a user's manipulation, and a shaft connected to the simulated bowel movement and positioned in the torso.
The doll also may include a head connected to the torso, and the drive mechanism may be positioned in the head and is configured to push against the shaft to extend the simulated bowel movement out of the opening in the torso.
A coupling may be connected between the drive mechanism and the shaft.
The coupling may be configured to permit rotation of the head relative to the torso.
For example, the coupling may be a ball-and-joint socket.
The drive mechanism may include first and second components coupled to convert axial motion of the first component in a first direction to axial motion of the second component in a second direction.
Axial motion of the first component may be induced by an object (e.
g.
, the end of a bottle) inserted into the doll's mouth.
Axial motion of the second component may cause the second component to push against the shaft and extend the simulated bowel movement out of the opening.
Relatively smaller axial motion by the first component may result in relatively larger axial motion by the second component
