New Wave Bossa Nova

The "New Wave Bossa Nova" is a song featured in Majora's Mask. After Link places the seven Zora Eggs that he rescued in the aquarium located inside the Marine Research Laboratory, the eggs will hatch and line themselves up according to the notes that make up the "New Wave Bossa Nova." Link as a Zora must take out his guitar for the baby Zoras to teach him the bossa nova. Once learned, the young hero must play this melody as Zora Link in front of Lulu to recover her voice, which will in turn awaken the giant Turtle who will grant him access to the Great Bay Temple.
