(Hape $16.99 each set)
For Quadrilla builders there are some new add-ons that will add new dimension (and maybe re-ignite interest) to the original set. The Sonic Playground ($16.99) is a five-piece set with 8 marbles to that run over the Xylophone that can turn the Quadrilla set in to a music making toy. OR consider the 9-piece Skatepark ($16.99) set with eight marbles, with a bright orange slide and cup.
Ages: Older Preschoolers, Early School
