Although many wing items in Club Penguin had "back" paper swfs that when viewed on a Player Card showed the portion of the item behind the penguin, without overlapping other items, this item's front paper swf was identical to the back paper swf, instead of being invisible, causing it to improperly overlap other worn items.
There was an alternate version of this item that was never released. Its front paper swf was invisible and it had no sprites.
Due to the front paper swf being invisible, thus only causing the back paper swf to appear, it displayed properly on a Player Card when worn, unlike the regular version.
