| 1997 | Invention patented by Joseph Cernansky, George T. Foster, and Elliot Rudell on March 10th, 1997. Abstract: A toy device that leaves a liquid footprint as the device is moved along a surface. The device includes a housing that resembles a duck. Attached to the bottom of the duck is a roller that can rotate relative to the housing, so that the toy can be pushed or pulled along a sidewalk or other similar surface. The housing is connected to a handle that allows the user, such as a small child, to move the toy along the surface. Attached to the roller are a pair of sponge pads that are constructed to resemble the feet of a duck. The sponge pads are soaked with water and leave a liquid pattern when pressed into contact with a surface. The sponge pads are located on the roller, such that a duck foot shaped pattern is left on the surface each time the user moves the duck and rotates the roller. The duck toy also includes mechanism for allowing the user to generate sound and move the duck's head up and down to further generate bubbles. |
