Dodoh's Gratitude Request/Dodoh's Minigame
When you've gotten the Clawshots, go to the entrance to Lanayru Desert(but speak to Dodoh on his island first) and activate the Time Stone. Climb up the vines, or Clawshot up, and walk along the ledge. Slowly make your way across the gap, and look for a rainbow wheel. Get closer and have Fi call the robot. Walk down along the ledge to grab a chest, and return to the sky. Fly over to the island and give Dodoh his wheel. He will unlock his minigame for a Heart Piece, lend 5 Crystals, and let you try his game once for free.
For the minigame, you will be blasted up and forced to dive back down. Hit the rings in the sky to rack up mulitpliers, and dodge the Dodoh Balls. If you can land on the 50-Rupee space with a 10x modifier, you get 500 Rupees and a piece of heart.
Finally, there is a Goddess Chest under the island.
