What r Bakugan?

Well a Bakugan is a small ball that transforms into a beast. Of course this wouldn't happen in real life, but they do sell bakugan at stores (walmart,target,etc.) and they open up in minturized figures of the bakugan. There is also a show of it called bakugan (cartoonetwork) and it airs Saturday mornings at 10 o' clock. So far they had three seasons, while the third season is in progress. They are called Bakugan, Bakugan:New Vestroia, and Bakugan:Gundalien Invaders.
