Abstract: An apparatus comprising a toy kit includes at least a pair of symmetrical-ended members, a cross-shaped member, and a dual-purposed member. The pair of symmetrical-ended members include two curved members that are mechanically coupled via spheroid domes and ball joints located at each end of the symmetrical-ended members. The cross-shaped member includes multiple shafts having a ball joints or spheroid domes at each end of the shafts. The dual-purposed member includes a shaft having a ball joint and spheroid dome at one end of the shaft. The spheroid domes and ball joints are deformable to enable mechanical coupling in which more than half of the surface area of the ball joint is wrapped by the spheroid dome and producing a unique sound when coupling.
