Air

Air
Air is anything which is not terrain. There are many different types of air.

Light
Light is anything that isn't terrain. It appears in most levels, and generates from Head Lights and Lamp Lights. It removes Darkness from The Road to El Porkado.

Wind
Wind is Light, but it pushes parts with a weak force. It is only found on some When Pigs Fly levels. It has leaves blowing to the direction the wind is blowing. It effects the Balloons most, due to them so being lightweight.

Fan Wind
Fan Wind is the same as Wind, but generates when Large Fans are on. It gives a much stronger force.

Darkness
Darkness is the opposite of light. It obstructs the view of the player, and it removes the terrain, even if it is still there. If Night Vision Goggles or the Alien Variant of the Lamp Lights are used, it turns green. The terrain will become visible, and so will the Bat Pigs.
