This frog is 4.5 inches along the ridges, from the tip of his chin to his tail; and 2 inches tall. Hold him in the palm of your hand, so he faces the same direction you do. To make hip chirp, rub the wooden plectrum over the ridges on his back. It`s important that you rub from tail to head. If you want to make him ribb-it, rub the plectrum from tail to head and then back down a couple ridges; all in one fluid motion. Now you can change the tone of the rib-it by covering and uncovering the holes at each side of his smile.Hold him nice, don`t let him hop away!
