Arctic White was first mentioned when the What's New Blog stated on April 20, 2012, that "an upcoming white color will be released."  Further information on the color Arctic White was not released until November 2012, when Polo Field revealed that all players will be able to get it before the end of 2012.  After the Holiday Party 2012 ended, it was permanently available for all players in the Penguin Style catalog.
Some penguins managed to get this before December 25th.
You cannot create an account and choose this color as a starting color, due to it being a bug.
When picking up the item in March 2012, there is a grammatical error. It reads, You have found a Arctic White. Would you like to pick it up? instead of, You have found Arctic White. Would you like to pick it up?
There was an error during the Holiday Party 2012. If you clicked to wear the Arctic White on your Player Card, it would say: "This item is currently unavailable." This is now fixed.
When Arctic White was first found in Club Penguin files before the Earth Day 2012, it was thought to come out then. This was proven false, however.
After the Earth Day, Billybob announced it HAS been confirmed, and would come in a few months. Unfortunately, this only tempted hackers to hack it more, because a few months would probably be a long time to wait, especially for greedy hackers.
There was a rumor that it would be the ultimate prize at The Fair 2012. This was also false.
Finally, it was confirmed it would come in December 2012, and it became a Holiday Gift.
