The Fluffy Dimension is the first dimension (other than Normal, of course) that is introduced to the player. It makes the weight and mass of all the objects in the environment ten times lighter. The Fluffy Dimension is introduced in the Blue Wing along with the Heavy Dimension, its direct opposite.
Objects and surfaces are given a white, plush texture that show how much mass has been lost between dimensions and how objects will then be affected differently by the player. safes will be light enough to carry and be blown by fans as easily as a cardboard box , and can be thrown into great distances that are innavigable to the player.
