After 3 months of the previous edition, Club Penguin Rewritten has released a new Snow & Sports Catalog. To find it, waddle over to the Stadium and click on the icon at the bottom right.
Click on the football to get a Green Soccer Jersey.
Click on the penguin’s foot to get a Yellow Cheerleader Outfit.
Those are all the cheats! I’m not sure when the next Snow & Sports catalogue will be released. I’m guessing it’s December when the Ice Rink comes.
