Using your Deka Bakugan is easy! First, take out the included large GeoCore. Then, roll your Deka Bakugan across the GeoCore and watch it pop open into its battle - ready form. To play the trading card game, just use the included character card to face off against your friends. When it comes to maintenance, keep your Deka Bakugan away from water as it might damage the toy. Also, avoid dropping it from high places to prevent breakage. Store your Bakugan and cards in a dry place when not in use. This will help keep them in good condition for you to enjoy your Baku - Action adventures for a long time.
