The Air Tree is special tree which grows in Area 8's Nightmare Hill within Gourmet World whose fruit gives birth to air and is an essential part of the Phantom Beast Heracs' lifestyle. Air Trees can also be found in the Area 7's Underground Forest. When they are born, the ratio of components in the air is different so there can be dense oxygen, carbon monoxide or carbon dioxide. If proper fertilizer is given to the tree, more good quality air can be produced. Only a strong life force can become fertilizer for this tree. It's also an ingredient but it's a "Super Specially Cooked Ingredient".
