Abstract: An expandable and changeable playset building system with at least one retained playset member, which may comprise a resiliently compressible panel, and at least one squeeze connector, which may be formed from a pair of opposed gripping surfaces, for selectively retaining the retained playset member by frictional engagement. An interactive base connector unit can be provided that simulates a structure, such as a bridge, a tree, a fence, a merry-go-round, or a parking gate, in miniature and in three dimensions. A plurality of squeeze connectors can be coupled to the interactive base connector unit for retaining a plurality of retained playset members. Also, first and second squeeze connectors could be rotatably coupled together. Further, a plurality of squeeze connectors with a plurality of different orientations could be fixedly joined to form a fixed universal connector.
