Moonwalking refers to a glitch found in Sierra games where the player animation does not represent the direction the player is heading on the map. Typically, the glitch is performed by following a certain set of instructions or attempting to perform an action while going from one screen to the next. Details will be provided with each instance this occurs.
Vehicle Disembarking
This only applies to few screens in Police Quest II. To perform this, the player must press a directional key as the game loads between the in-vehicle screen and the location screen as Sonny gets out of the car. If done right, the player will start to move in a direction, regardless of which way he is facing, which can result in the glitch happening.
Depending on location, the player may or may not clip through walls.
