Using the Blast Attack Ghast action figure is easy. First, find the button on the top of the ghast. When you press it, you'll hear exciting whooshing and battle sounds, the lights will turn on, and the blast projectile will launch. You can use the included piglin warrior to recreate the epic movie scene. As for maintenance, keep the set away from water to prevent damage to the sound and light features. Don't apply too much force when pressing the button to avoid breakage. If there's dust on the figures, you can gently wipe them with a soft cloth. Remember, this set is suitable for kids aged 6 and up, so adult supervision is recommended for younger users.
