The Happy Hamsters Starter Set is a fun construction set for children ages 3 and up. Build the marble run and let the hamsters race through it! Get started building the slide. Follow the steps in the instructions to build the "half-moon" or "zigzag" route. Or use your imagination and create your own! Ready to go? Place one of the adorable hamsters on top of the slide and give it a push. Watch it slide down! Play with the stunts the hamster performs along the way—only then will it reach the end of the track.
