The puffles now play with furniture that you buy for them in the Club Penguin Puffle Furniture catalog. To get them to play with the new furniture, click on your puffle and then click on the play button which is the little beach ball in the bottom left. The puffle will choose one of the pieces of puffle furniture in your igloo to go play with.
They will climb up and swing from scratch towers and other toys, sleep in their beds and drink water from their bowls.
Remember, there are two catalogs in the Pet Store for puffles. One is to adopt the different puffles. That is the red puffle catalog. The other is to buy the furniture. That one is the orange puffle furniture catalog. They both say PETS on them.
