Using the Spidey and His Amazing Friends Power Smash Hulk action figure is easy and fun. To start, just press down on Hulk's head. You'll see his facial expression change from happy to powerful, and his arms will move up and down. You can use him to knock down the included two - piece wall accessory. After knocking it down, kids can have a blast rebuilding it and repeating the action. When it comes to maintenance, keep the action figure in a clean, dry place away from sharp objects to avoid scratches. Don't expose it to extreme temperatures as this may damage the plastic. If it gets dirty, you can use a soft, damp cloth to gently wipe it clean. Always make sure kids play with the toy under adult supervision to ensure safety.
