Rollo the rolling and laughing dog will have you in absolute stitches. His laugh is so contagious you will not be able to help but laugh along with him.  Once you have turned Rollo on he is motion activated, so all you have to do is move your hand in front of the sensor in his head. Rollo will then start rolling around and his mouth will open and close in fits of laughter. If you pick him up in the middle of all this hilarity he is just about impossible to hold onto as he twists and turns in your hands. Great fun, Rollo measures approximately 30cm in length and requires 3 AA batteries which are not included. China supplier: Email : fangzhengcn@hotmail.com Skype ID : chanceller819
