The Catchin’ Waves Upgrades catalog was released towards the end of March 2009. In the catalog you can currently buy three items. All are Surfboards for the game Catchin’ Waves. The surfboards are all hand items. If you wear one of them in Club Penguin, you’ll use that one when playing the game rather than the regular surfboard it does by default. This catalog had a hidden item in it, the Silver Surfboard.
