Nothing major, but it looks like Club Penguin is going to release a new igloo this month! UPDATE: See the igloo here.
I was looking at the game configuration files earlier today when I saw a reference to an unreleased igloo. This igloo, called the Beach Party Igloo, is going to cost 1,500 coins. Unfortunately I don’t have a picture but on the plus side it’ll keep us guessing as to what it looks like!
