A clock timer having a face comprising a mouth, eyes, a nose, and an arm secured to the nose. Rotation of the nose turns a shaft which, via a camming mechanism, forces a plate housed within the clock upward. As the plate moves upward, a rack formed in the plate drives a gear mechanism which rotates the mouth and eyes from a smiling orientation to a frowning orientation. Rotation of the shaft also rotates a timer housed within the clock. Upon expiration of the timer the shaft is rotated in the opposite direction, thereby lowering the plate, driving the gear mechanism, and rotating the mouth and eyes from their frowning orientation to their smiling orientation, and activating a bell housed in the timer.
