Using this Young - hee figure is super easy. First, you'll need to get 2 AAA batteries (they're not included, so make sure to grab them). Once the batteries are in, you can turn it on. Watch as the head rotates and listen to the key sounds and lines from the show. You can play the 'Red Light, Green Light' game with your friends right on your table. As for maintenance, keep it in a dry place away from direct sunlight to avoid any damage to the paint or the motor. If it gets dirty, you can gently wipe it with a soft, dry cloth. Don't try to open it up yourself as it might void the warranty and could be dangerous. Enjoy your amazing Squid Game collectible!
