A doll that may be actuated to simulate a swimming, walking or kicking action includes a torso with a pair of arms rotatably mounted thereto. A head mounting member is pivotally mounted to the upper portion of the torso and a leg mounting structure is secured to the lower portion of the torso. A pair of legs are pivotally mounted on the leg mounting structure in a manner to allow independent rotation. A compound cam is rotatably mounted in the torso and includes a helical groove in which a pair of cam followers are positioned that are in turn secured to each of the legs. A third cam follower is positioned within the torso to engage an eccentric cam that is part of the compound cam. The third cam follower is mechanically connected to the head mounting member resulting in pivoting of the head. A flotation device is arranged to be engageable by the doll's arms for use in the swimming mode. The doll may also include a wheeled vehicle that supports the doll in a generally vertical orientation while allowing the legs of the doll to engage a surface such as a floor. Movement of the legs propels the doll and the wheeled vehicle over a surface.
