Wallpaper Shop
From The Wajas Wiki
The wallpaper shop is found under the shop link in the world menu, and restocks at :02, :17, :32 and :47 past the hour (except between 1am-2am wajas time when there are no restocks). This is where some wallpapers can be bought, although not all wallpapers are available through this shop. Some wallpapers are available for short periods only, but others are semi-permanent.
