I'm guessing they have their pinchers banded, or it would be really easy to win that one... Just drop the claw and you'd have three of them dangling off of it! They could even take it one step further and have a boiling pot of water on the other side of the crane so that it picks them up and drops them in for you. I bet PETA would love that!
Oh you cold-blooded monster sir fotosdenada! lol. That's a cool idea since they're going into the boiling pot anyway!
