A manually manipulatable flexible toy includes an elongated tube unitarily fabricated of semi-rigid material such as plastic. The tube forms bellows which, in turn, define a plurality of larger diameter rings and a plurality of smaller diameter rings joined in an alternating array lengthwise of the tube by frusto-conical walls. The tube or any portion thereof is extendable and retractable and manipulatable into various curvilinear configurations, with the tube maintaining its last chosen extended or retracted or curvilinear condition. A pair of the frusto-conical walls diverge radially inwardly from any given larger diameter ring to an adjacent pair of smaller diameter rings when the tube is in the extended condition. A pair of the frusto-conical walls extend radially inwardly offset to one side of any given larger diameter ring when the tube is in the retracted condition. The tube is of a length sufficient to be curved into a closed configuration such as a circle and the like. Opposite ends of the tube are capable of being telescoped and coupled together.
