Get ready to race through the rainbow! With this beautifully interactive Rainbow Musical Ball Run Assembly Set from Grimm's Spiel & Holz, children can create their own ball run based on whatever color combination they choose.

Once the ball run is built, a double spiral run allows for races and kids can determine which ball is the most quiet as it rolls and which one is the loudest or which one is the fastest!

After many races and much fun, the ball run can be taken apart and rearranged in a different color set-up, so the fun can begin again. A wonderful toy that will grow with your child and provide hours of open-ended play and creative building experiences.
