Weplay Apple Links is a building block set consisting of lightweight green and red plastic cubes (Apples), 2 sizes of brown plastic bumpy rods (Caterpillars), green foam ovals (Leaves), and a plastic needle (Needle Caterpillar) and thread. The Apples have varying holes for threading and inserting (clicking in) Caterpillars. Connecting Apples and Leaves via Caterpillars or thread allow children to build their own abstract creations or representations of other real-world objects. The set contains more than 80 pieces, making it ideal for interactive partner play or individual exploration of creativity and construction.
