A pop-up crib toy including a head mounted on a rod with a cylindrical gear rack. The rod is slidably carried in a tube included in a housing for a motor driven gear segment. Engagement of the teeth on the gear segment with the cylindrical rack drives the head up from the housing in opposition to a gravity bias which lowers the head upon disengagement of the gear segment teeth from the rack teeth. In the wall of the tube a serpentine slot is provided in which a pin carried by the rod rides to turn the head from side to side as it moves up and down. L-shaped paws extending from the housing hang the character over the edge of a crib.
