The toy box is a cube-shaped object that pulls out a clown head after cranking it for a certain amount of time, usually depending on how fast it is being cranked. The face of the clown appears white with orange hair and a red nose. A light green spring is attached from the head to the bottom of the box.
The inside of the box is blue, aside from its the outside which contains multiple colors including velvet, green, and yellow. The box has a crank located on the side, and when it is turned, it plays a tune which follows to a pop.
