Using these Charapaki Gochizos is a breeze. First, pair them with the DX Henshin Belt Gavv or other compatible items from the toy line (you'll need to buy those separately). Just insert them into the appropriate slots to see all the fun features come to life. When you're done playing, store them in a cool, dry place to keep them in good shape. Avoid exposing them to extreme heat or cold, as this could damage the toys. Also, be gentle when handling them to prevent any breakage. Have a blast with your new Charapaki Gochizos!
