Skyward Sword‘s big unique sidequest system is the Gratitude Crystals sidequest, which involves doing good deeds for the various peoples you meet throughout your quest. You can think of it as a combination between Twilight Princess‘s Poe Souls and Majora’s Mask‘s Bomber’s Notebook in that you’ll get crystals for helping characters with their problems. Be vigilant as you meet NPCs - any of them could offer you Gratitude Crystals if you interact with them in just the right way.
Bring your collected Gratitude Crystals to the friendly demon, Batreaux, who wants to use them to become human, and he’ll give you various rewards as thanks. These include capacity upgrades for your Wallets, Satchels, and Pouches, as well as other goodies.
As part of our Skyward Sword Walkthrough, we’ll be delivering a full-blown log that keeps track of the locations of every single Gratitude Crystal in the game so you can make sure you track down each one and complete all the related sidequests. There are sure to be tons, so double-check periodically if you’re not sure whether you’ve missed a few!
Most Gratitude Crystals come from helping others with their troubles. In these cases, they come in groups of five, but they can be quite challenging to figure out. You can spot people who need help and who can assist you in helping others by looking for the talk icons above their heads as you approach them.
Sometime after you unlock the path to Eldin Volcano, Kukiel’s parents will inform you that she has gone missing. You can follow clues to the old man in the Lumpy Pumpkin, who knows something about a demon who haunts the Skyloft graveyard. Strike the tree nearby the top-leftmost grave and the tombstone will start glowing. That’s your cue to give it a good shove, which will open the shed door nearby. Drop down the ladder inside to reach an old decrepit house. Inside is Batreaux, the friendly demon. Kukiel’s been keeping him company. She’ll return home the next morning and you can receive five Gratitude Crystals from her mother.
Orielle has gone missing. She was last seen flying towards Fun Fun Island, but she seems to have disappeared en route. You’ll find her on the small round island between Skyloft and Fun Fun Island. She’ll ask you to talk to her brother, Parrow, who is looking for her, and retrieve a bottle of mushroom medicine for her bird. Bring her the bottle and she’ll let you keep it, as well as pass on five Gratitude Crystals. Talk to Parrow later for five more.
The bathroom in Skyloft seems to be haunted - strange noises come from it at night, asking for paper. (I wonder what for?) You can retrieve some from Cawlin if you agree to deliver his letter. At that point, you have two choices - bring the bathroom ghost the paper she needs, or take it to Karane as promised. Either path will result in you earning five Gratitude Crystals.
Fledge looks up to you, and so he’s trying to get stronger with a nightly workout routine. He needs more endurance to make it through however, so he asks you to bring him a Stamina Potion. Do so once and his workout ethic will improve. Later on he’ll ask for a second potion, and if you comply, he’ll eventually build up enough strength to pass on five Gratitude Crystals.
Head for Pipit’s House at the northeastern part of Skyloft. His mother has let the house fall into a ruined state, but you can use the Gust Bellows to clean up. Make sure you clean every dirty surface, including the windows, beds, and dressers. You’ll get five crystals as thanks.
Bertie runs the Potion Shop with his wife, Luv. He’s stuck taking care of their infant child, who doesn’t seem to want to sleep through the night. You’ll need to find his missing Rattle to calm the young babe. Use your Clawshots to grapple up to the floating waterfall island, accessible from nearby the entrance to the Waterfall cave, then skydive onto the bird’s nest atop the tower nearby the Bazaar. Use the Gust Bellows to clear out the nest and pick up the Rattle, then deliver it to Bertie for five Gratitude Crystals.
Sparrot the Fortune Teller will at one point break his crystal ball. He’ll ask you to find a replacement, which is no problem if you have the Clawshots. Simply grapple up to the top of the entrance of the Earth Temple with the Clawshots and approach the round shiny orb. Scrapper can bring it back up to Skyloft for you, at which point all you need to do is approach Sparrot and you’ll receive five Gratitude Crystals for your troubles.
Kina of Pumpkin Landing hopes to find someone to help plow the Pumpkin Fields. The person she’s looking for is the Mogma Elder, who is waiting on one of the tall stalagmites jutting up from the caverns below Eldin Volcano. Skydive nearby him and Scrapper can bring him up to the sky. He’ll perform so well as his task that Kina will produce five Gratitude Crystals.
Dodoh of Fun Fun Island wants to run a family-friendly minigame joint, but he just doesn’t feel up to the task without his “fun wheel.” Turns out it fell off the island and landed in Lanayru Desert. Dive down to the first Bird Statue you ever found in the desert proper. Strike the Timeshift Stone there to create a series of vines leading up to a ledge above, then make your way over to the Fun Wheel and have Scrapper carry it back into the clouds with you. Dodoh will be so happy he’ll give you five Gratitude Crystals as thanks.
If you frequent the Item Check, speak flatteringly to Peatrice and she’ll start to fall for you. Keep indulging her to the very end and her father will ask you to figure out who’s bothering her. Talk to her a final time at night in her house and she’ll confess her undying love for you and give you five Gratitude Crystals.
Owlan loves studying rare plants, but there’s only so much to examine in Skyloft. He’s looking for a new specimen. If you talk to Machi the Kikwi, who’s still convinced he should be hiding, he’ll agree to come up to Skyloft with you. You can find him in the grove where the Kikwi decided to settle down after you cleared Skyview Temple.
Talk to Beedle as you approach the ending hours of the game and you’ll learn his precious beetle has gone missing. Turns out it was recovered by Strich, who will only surrender it to you if you clear his insect-finding gauntlet in the Thunderhead. To win, you’ll need to collect certain predetermined insects within a three minute time limit. The best route is as follows:
Return the Beetle to Beedle on his island at night and he’ll give you five Gratitude Crystals.
Single Gratitude Crystals appear only at night, meaning they’re only in areas where you can fall asleep. You can find them at the following locations:
