Abstract: A toy convertible between a doll walker and an activity play board includes a base having at least one wheel, and activity components and a seat formed in a first main surface of the base. A pair of bosses project laterally from the sides of the base, and a pair of wheeled legs attach to the base by engaging the bosses in boss cavities and with a fastener. By selecting the appropriate boss cavities, the base can be either horizontally oriented or inclined relative to the horizontal.
