To use the Groove 'N Grow Groot action figure, simply press the leaf button on his foot to watch him grow from 13.5 inches to 18 inches. You can play music, talk, or make sounds around him, and he'll respond with a cute dance or say 'I am Groot'. Pose him with his moveable head and arms for playtime or display. Remember, this toy is for kids 4 and up. Be careful as small parts may be generated. Batteries aren't included, so you'll need to get your own. It only speaks English. After playing, keep it in a dry place to maintain it well.
