How to use: First, take out your Bakugan from the pack. Roll them over the BakuCores to make them pop open for Baku - Action. You can also choose your Bakugan Ultra and watch it do an epic transformation. Use the Gate - Card to add more fun to your games and get bonuses. When playing with friends, collect all the different Bakugan characters. You can trade them to expand your collection. Note: Be careful when rolling the Bakugan to avoid losing the small parts like the BakuCores. Keep them in a safe place when not in use. Maintenance: Wipe the Bakugan with a dry cloth if they get dirty. Don't use any harsh chemicals as they might damage the details and symbols on the Bakugan.
