A twist-and-release floor toy. Set it on a clear floor, twist the side knob clockwise up to two turns, then let go and it rolls forward on its own wheels. Assembly and winding call for adult supervision, restraining the knob until release.

Twist the knob, release the roll. Turn the side knob clockwise, up to two full turns from relaxed, winding a silicone cord threaded through the hollow axle and tied off at the fixed anchor and at the axle's own crossbar. Release the knob and the stored twist spins the front wheels while the two free rear rollers trail on their pins.

Twenty parts, fitted together. Twenty separate pieces make the duck: a central frame carries the head rim, eye ring, dark eye disc and oval sensor up front, plus the neck cover and bill. Boot, sole and shin covers dress each leg, and the axle-and-knob, left drive wheel, fixed anchor and paired rear rollers on pins carry the drivetrain, each piece fitted to its own seat.

Made in PETG. Made in PETG, the assembled duck stands about 7.1 inches tall, 3.4 inches wide, and weighs 0.2 pounds across its twenty parts. The grey shell, yellow bill, and purple eye ring and accents are dry-fit before bonding.
