Just managed to get an in-store order in for this one... hopefully when I get there they will magically have the Scanning Crew set on the shelves. There's nothing more inconvenient for me than K-Mart exclusives.
This thing REALLY launches those rocks, which are rubber... like, not even vinyl. They're rubber, like slightly more rigid super balls from the bubblegum machine... They bounce nice, but man, this thing will launch them hard. Cats/dogs beware.
