If you go to the Snow Forts, as long as your cache has updated you’ll see some construction at the Snow Forts for the SoundStudio Party. (and even though mine has I still don’t see it, yet I see the new newspaper and new furniture catalogue…too many bugs Club Penguin, shame on you) There isn’t much to the construction: some blueprints, a crane, a few boards, shovels, and a mallet. Due to the construction one of the forts is temporarily gone. For those of you who can’t see the updated Snow Forts on Club Penguin like me, here it is: UPDATE: Finally, after four days, the update appears for me in-game.
The SoundStudio Party begins next week on the 19th of February. Along with the party will be the release of the SoundStudio app.
Thanks to Saraapril for bringing this update to my attention.
