Fourth Wall

A fourth wall is a figurative term, being described as an imaginary wall. To break the fourth wall, a character is able to talk aside or stare at the audience (you), or the character will get too close to the screen. The fourth wall occured in theatres or plays in art.

In Shorts

• In Lil Rob's short, Rob takes his first appearance to look at the viewer, and gives a thumb up, before preparing to skate. This rarely means that he is the first to break the fourth wall.
• Goggles' short let the entire Wild Grinders gang look at the viewers with the camera. Especially, Emo Crys gets dragged to the machine, as his face is on the screen, with his snot sticking in it too.
• Jack Knife always look at the viewer in Goggles' camera in his own short.
• Near the end of Spitball's short, Spitball stares at the viewer, before performing a battle cry.
• In Pebbles, the baby nearly looks at the viewer, before he/she begins to cry.
• In Concrete, the beginning of it shows Lil Rob looking at the viewer, while skating pass the driver who curses at the trio.

In the older version of the website

• Every character, except for Meaty, are looking at the audience.
