Where do you get the backgrounds?

What kind of backgrounds? Avatar backs?

The backgrounds like oceans or forest lol.

The avatar backgrounds are just items that can be obtained the way items are normally obtained. The scenery ones that I think youre talking about are iften kind of rare and can get expensive depending on the one in particular you want. Most of the backgrounds are fest items that can be obtained during their specific fest. New backgrounds may be gotten through defeating their respective bosses or possibly by buying them from the fest store. Some backgrounds were only given out for winning or participating in certain forum games. If you want more specifics youll have to let me know which backgrounds in particular youre interested in.
