Any character viewed from far away is represented as a rectangle, with the color changing for each character. For instance, Gumball is blue, Darwin is orange, and Banana Joe is yellow.
That's not what you are, it's just how you feel.
The color of some of the character's mouths change from red to black in some episodes.
Much of the show's more vulgar scenes are cut out in airings in the Australian, Filipino, Latin American, and Arabic versions. Some of the episodes have never aired as well. In Turkey, Bulgaria, Poland, Japan and Spain there are some cuts as well.
