My son has recently become obsessed with these after watching countless videos on Youtube. I just don't get what is so cool about them. First of all, they are pretty expensive for what you get. $3-$4 each is pretty steep for a little toy that doesn't even really do anything. I get the whole "surprise" concept is excited to see which one your going to get. It was a great idea by whoever created them, because you get people to spend more and more money on them. The fact that you don't know which one you are getting, so you keep buying more and more to try to get one you don't have. Only to find out, you just added a sixth freaking Venom to your collection. Waste of money if you ask me.
