Original Commentary
There's a place we go that has a very similar claw machine, and Isabel has a selection of pastel bunnies and kittens. There's a knack to knowing when the claw is too loose and you should just give up - Terrence

Modern Commentary
Claw machines are set so that they'll only give a firm grip one out of every ten plays or so.

There's strategies to them and ways of making the most of when it does cooperate. But sometimes, nothing you can do for it. - Terrence
