I managed to buy the Gormball Background.

So how to 'wear' it?

1. Put the item to the closet.



2. Go to your pet lookup page.

3. Click "Customization".



4. Double-Click on the background.



5. It will appear on the left column.



6. Click "Apply".



7. Click "Save Changes" on top.

Enjoy.

Psst... doesn't she looks like she just pee on the floor?

6. Go to your inventory and it will be there now.

7. You have removed the background.
