Abstract: A push or pull toy (walker toy) comprises a hollow body simulating the body of an animal and formed with a transparent or semitransparent window, wheels for supporting the body and enabling transport thereof over a supporting surface in response to an applied force, and a dual ancillary movement generator having a first branch adapted to effect a nodding of a simulated animal head connected to the body and a second branch adapted to effect the pop-ejection of marbles or balls that are contained within the body and visible through the window.
