Abstract: A noise generating clapper apparatus includes a main body sheet having a plurality of foldable flaps, the plurality of flaps having a front flap attached to a rear flap along a first fold line and a joint flap attached to the rear flap along a second fold line, and a clapper member pivotably mounted to the joint flap. The joint flap folds along the second fold line and the front flap folds along the first fold line to enclose the clapper member between the front and rear flaps in a secured position. The main body sheet is maneuvered in a shaking motion to permit the clapper member to pivot between the front and rear flaps, thereby enabling the clapper member to generate noise upon contact with the first fold line of the main body sheet.
