Recently, on the disney.co.uk/clubpenguin page, they have changed it for the Ultimate Jam and added a video of Rocky and CeCe promoting Club Penguin (they were probably paid!). On there, the igloo is clearly shown. See for yourself!
Could it come, it looks awesome, however look, it has the old edit igloo and spy phone icons, and the igloo covers the chat bar, so its an unfinished game picture. I also think the the Pineapple igloo, which is unlockable from the innocent smoothies, may be two storey, as the floor on a Pineapple is very small, so it may have 2 floors!
Do you think my theory is good? Do you love this igloo too? Have you seen the video? Let me know in the comments.
