PLEO is an animatronic pet dinosaur toy manufactured by Innvo Labs, a company located in both Hong Kong and Nevada. The toy has the appearance and (imagined) behavior of a week-old baby Camarasaurus dinosaur. It was designed by Caleb Chung, the co-creator of the Furby, Chung's company Ugobe first sold Pleo and was manufactured by Jetta Company Limited. The species of dinosaur chosen allows for concealing the sensors and motors needed for the animation, since it has a big body shape and relatively large head.
