Fourth Wall

The term "fourth wall" originated from plays in theaters, when actors would look at the audience, talk to them, or do anything else that involved the audience. Because the stage would generally have a wall at the back and both sides, this concept involves the actors becoming involved with the audience who are at the front, which can be considered an invisible wall, making it the fourth one.
Sometimes in Happy Tree Friends, something will happen that implies the characters are aware of being fictional characters in a cartoon. The Fourth Wall is most often broken in Smoochies, but has also been broken in the internet series and the TV episodes.
