An animated toy box assembly for stimulating a child to put away toys includes a box that may contain toys. A lid is hingedly coupled to the box such that the lid selectively closes the box. A pair of eyes is coupled to the lid to resemble monster eyes. An interaction unit is coupled to the box and the interaction unit selectively emits audible sound. The interaction unit detects motion thereby detecting when toys are positioned in the box. Moreover, the interaction unit emits the audible sound when the interaction unit detects motion. In this way the interaction unit stimulates a child to place toys in the box.
