Ocarina

The Ocarina is an instrument that you find in the game. It is required to unlock certain parts of the main story. As Orange Heroine, it's replaced with the Spirit Flute.

HOW TO FIND: Go south of the Castle in Chapter 1. Enter the Tall, Tall Mountain level and get to the top. Dig the spot marked with an X. You will find the Dirty Ocarina item. Return to the castle and go to the moat. Use the Dirty Ocarina with the moat to clean the dirt out of it. It will turn into the Ocarina. Now you can open the cage containing the final level before the 1st boss, Lethal Lava Land.
