NewGame: Change your profile picture to your favorite cartoon from when you were a kid. The goal of this game is not to see a human picture on Facebook, but an invasion of childhood memories until Monday. PLAY AND PASS ALONG!

Another Facebook user posted the following instructions:

From the 12th to the 22nd of November, change your profile picture on Facebook to an image from a cartoon from your childhood. The goal of the game?
