This 2-in-1 toy from Yookidoo develops hand-eye coordination and cause-effect play when they play with the detachable bead coaster cylinder that rolls as beads slide on duck's back. Kids will not resist those darling little ducky eyes staring right back at them, they want to spend lots of time with their new pal! It also includes a pull along string that enables the kids to go with the toy wherever they go as they develop balance and coordination.
