It wouldn't be a Zelda game without collectibles, and there are a ton of them to find in The Legend of Zelda: Skyward Sword HD. In addition to series staples like pieces of heart and bottles, Skyward Sword features a variety of unique collectibles to get your hands on, including monster parts and Gratitude Crystals. The latter are particularly valuable, as they can be traded to a certain character for helpful rewards and upgrades.
While a handful of Gratitude Crystals can be found out in the open, you'll primarily receive them after helping the various residents of Skyloft with their problems. That includes Dodoh, the clown from Fun Fun Island. Below, we've broken down how to complete Dodoh's side quest and earn his Gratitude Crystals.
