We bought V this Bakugan set as a prize for doing well in his first school concert, he’s been saving every coin he finds around the house to be able to buy one.
They start out as ball and when you place or roll them on top of the cards they change to this “robot” like thingie. I spent a good 2 hours trying to figure out how to put them back.
If you find one mommy with a box of this little ball monsters that’s probably me.
