This is my first mod that changes the appearance of a ball (actually lots), and probably the last one, because I got bored! 
NOTE: I only edited the body images because I don't know how to use PhotoShop or GIMP properly, so I'm sorry if some of these changes look awful. I got these images from somewhere else. Is Paint.NET a good software for someone like me? (lol)
What are the new balls?
#1 balls are Common.
#2 balls are Albino.
#3 balls are common black, and Distant.
#4 balls are Pixel, SimCommon and DrainedIsh.
#5 balls are Pilots.
#6 balls are Ivies.
