Fakebook is a social networking website which is frequently used by the show's characters, mostly Stumpy and Pretty. It is a parody of the real-life website Facebook. In the show's French dub, it is called "Face de Bouc", which literally translates to "Goat Face".
In "Let's Play Prince Charming", Stumpy looks for a girlfriend on the site, only to meet somebody who wants to steal all his money. In "Let's Play Hot - Cold", he mentions meeting Ursula on the site, and he uses Fakebook to send her a heavily edited picture of himself. In "Let's Play Party", Mr. Cat uses it to show Quack Quack fake pictures of Eugly cheating on him with some of the other characters.
