Disclosed is an ornamental toy capable of running up and down mainly including a driving mechanism wrapped up by the ornamental toy and a long bead string extending through the driving mechanism. The driving mechanism includes a motor rotating a driving wheel of a clamp wheel set, so that beads of the string passing through the driving wheel set are received in recesses formed on the driving wheel and are clamped between said driving wheel and an idler of the clamp wheel set, allowing the driving mechanism wrapped in the ornamental toy to climb along the bead string. Since the idler is co-axially connected to a link which will be pushed outward by a cam connected to a reduction gear set actuated by the motor, the idler will be moved away from the driving wheel at a fixed interval due to the contact of the cam with the link, causing the clamp wheel set to disengage from the bead string, allowing the driving mechanism within the ornamental toy to slide down along the bead string.
