About Us

Relevant Play, formerly Waba Fun, was founded in 2003. We are passionate about creating awesome toys for children, that encourage imaginative and open-ended play. We believe playing and learning go hand-in-hand and that it should always be fun!

With this vision, we brought to market numerous, award-winning toys to nurture the creative genius that naturally lies inside all children. Our compound products include Mad Mattr - The Unbelievable Dough You Build With, Kinetic Sand, Shape It!, and Toki Dough, a magical arts and crafts activity brand. To complement these we also have a range of innovative molds, like the Ultimate Brick Maker®, and accessories to further enhance the enjoyment! We are also introducing a new meaning to “Spring Training” with Coilz, an all new tactile collectible and game brand, as well as bringing STEM learning with Build A Bot, where you can build a robotic pet!
