sorry for the double post, but check this out

gamestop has them also

Something my kid and I can fight over. He's 4, and doesn't really play, but loves to watch.\r How much are they? Do you buy them individually or as a pack?

They come in a pack of 4 and are 19.99.

keep an eye out for a pack with a black one in it instead of a clear one. Rarer and much more collectable
