Bag of Winds

That Bag of Winds is a tool found in Sand Chests. It is used much like the Magic Mirror. In order to use it, the player will have to hold the "use" button for about 5 seconds, during this period of time, the bag will begin to suck in wind. After waiting for 5 seconds the player is then able to propel themselves through the air at an average speed for about 20 seconds
