Pipes of Awakening

The Pipes of Awakening, also known as the Deku Pipes, are the pipes that are used by Deku Scrubs in Majora's Mask. When you transform into Deku Link using the Deku Mask, upon using the Ocarina of Time, Deku Link pulls out the pipes instead. Also, when you are trying to save the monkey in the Deku Palace, you must take out the pipes to learn the Sonata of Awakening. It's sound is very similar, if not identical to, bagpipes.
