How to use: Open the pack and take out the Sonic and Knuckles figures along with the battle controllers. Teach your child how to hold the controllers and use them to make the characters perform their special moves like Sonic's High Kick and Knuckles' Fist Attack. Let the battle begin! Note: Keep small parts away from children under 3 to avoid choking hazards. Make sure to play on a flat and clean surface. Maintenance: If the figures or controllers get dirty, you can use a soft, dry cloth to gently wipe them. Don't use any harsh chemicals as they might damage the toys.
