You can't really work at the Puffle Shop. If you bought the puffle apron you can pour puffle food. You can't really work there because there is nothing to do there. You can pretend to work there but you can't work there to get money or to sell real stuff. Hope this helped!:)

In Club Penguin, you don't have to have any skills! All you have to do is bring a puffle and/ or put something on your penguin to make you look like a Pet Shop employee and walk around in a Pet Shop that has lots of Club Penguin "babies" and give some of the babies food, water, and/or toys. (Most of them like icecream, milk in a bottle, pizza and elmos).
