The Legend of Zelda: Majora's Mask Walkthrough

Majora's Mask p.3

DEKU FLOWERS
When you're ready, stand atop the flower and you'll see Tatl flash. You can press the button to get an explanation from Tatl if you wish. Press and hold the A button to dive into the flower, then aim with the Analog Stick and let go of A to shoot up and fly around using a flower in each hand. Who needs ladders? Fly over to the other side of the room and either wait for the "flower-power" to wear out or press A to drop down early. If you don't make it to the platform, use the flowers to work your way back up and try again. Once you make it, go through the door.
