The 13 in. Light and Sound Multi-Action T-Rex is a very interactive toy to encourage pretend play. The T-Rex has eyes that light up and makes realistic dinosaur sound effects. It has a poseable body to let kids create dynamic action poses giving it more flexibility during playtime. The T-Rex also has push button action. Push one button and roaring sounds with arm movement occur. Push another button and roaring sounds with jaw action is seen. Or push both buttons and all the moves are activated. You can play with this T-Rex alone or play with other light and sound toys in the collection. But watch out because this T-Rex has chomping action and can pick up prey easily with its jaws.
