An unreleased igloo background has been found in Club Penguin’s files, the new Undersea Igloo Background. Chances are it will be released next month in the November 2014 Furniture & Igloo Catalogue. Here’s what it looks like. It reminds me of the Underwater Adventure stage play.
The cost of this igloo background is unknown.
Thanks to Pen50gi for his help on alerting me about this and finding the image.
