A toy doll, posable and simulating stances or positions and movements of a skater, dancer or the like. The device includes a torso with arms and leg which may be frictionally pivotably connected to the torso to enable posing the doll in a wide variety of positions. The doll is supported atop a self-propelled base by engagement of a foot or skate, such as an ice skate, roller skate, roller blade or the like, with a platform which forms a portion of the upper surface of the base. The base is supported by a front wheel and by two spaced apart rear wheels. The base is propelled by one rear wheel and steered by a replaceable profile cam-guided front wheel. The platform is rotated along with the doll about an upright axis as the base is propelled over a horizontal surface through a repeated geometric pattern defined by the particular profile cam selected.
