Fourth wall

The fourth wall is a concept in video games. It refers to the division between the in-game characters and the player. Breaking this division is referred to as "breaking the fourth wall". This is often done with characters explaining controls to the player, or if the characters actively are aware they are part of a game, such would be that the fourth wall is not only broken, but destroyed to a point of no repair.

In the Banjo-Kazooie Universe, it appears that most (if not all) characters are aware they are part of a game, and therefore break the fourth wall constantly. The most extreme example of this is the presence of L.O.G., who appears as the creator of all games, including the one all the other characters are currently in.

Banjo-Kazooie

 * Bottles teaching you new moves and saying the buttons required. (i.e. press B or press Z)

Banjo-Tooie

 * "Watch it, this is a family game!" "Oh, so it is." - Banjo and Chief Bloatazin
 * "It's nice to know not every character in this game is bad." - Scrotty
 * "One more press o' that button an' I'll run ye through!" - Captain Blackeye
 * Jamjars teaching moves, similar to Bottles, which he now broke more because of using the button icons.
 * "Pressing the joystick only slightly will make you tiptoe silently" - Sign post in Mayahem Temple. (Breaks wall because signs say things like "ever check here?")
 * "Bottles taught us loads in the last game." Kazooie
 * "He wasn't the favorite character in the last game..." Kazooie, upon Bottles' death.

Banjo-Kazooie: Grunty's Revenge

 * Bozzeye's teaching, yet again.

Banjo-Kazooie: Nuts & Bolts

 * "I would like to keep you like this, but I believe the people would like to take part in this game" - L.O.G.
