Toys R Us is having a Bakugan Training Camp
Saturday, June 20th, 12-2pm
From the site:
Learn how to use Bakugan Trap
Training, Battles, Prizes & Giveaways
I have no idea what Bakugan Trap is, but if your kid's into Bakugan then s/he does.
Participation varies (there aren't any in STL), so check the site.
