A toy includes a head, a tongue, and a driving unit. The head includes a skull, an upper jaw fixed to the skull, and a lower jaw rotatably coupled to the skull and facing the upper jaw to cooperatively define an oral cavity. The tongue received in the oral cavity includes a tongue tip and a guiding rod assembly. The driving unit includes a driving shaft fixed to the skull, a rotatable disk rotatably coupled to the driving shaft, a first lever pivotally coupled between the rotatable disk and the lower jaw, a second lever pivotally coupled between the rotatable disk and the guiding rod assembly and a motor. One end of the guiding rod assembly is received in the tongue. The motor drives the rotatable disk to rotate such that the lower jaw rotates away from the upper jaw and the tongue tip protrudes out from the oral cavity.
