While looking at a Club Penguin stamp file I came across some information about the 2011 Halloween Party, which will be on Club Penguin in about two months. The unix timestamp points towards the party’s end date which will be sometime on or around November 3, 2011. The stamps you will be able to unlock at this party include but are not limited to Monster Mash, Explorer, Happy Party Room, and Tend a Concession Stand. The Monster Mash also has some unreleased items listed. I do not know the names of these items. You can view it below, although it is hard to read.
I love the Halloween Party!
