- "Crystallized feelings of pure gratitude. Gather them and show them to Batreaux."
- — In-game description.
Gratitude Crystals are items from The Legend of Zelda: Skyward Sword. These crystals are physical manifestations of peoples' feelings of gratitude; there are 80 of them in all, and they may be gained after completing various side-quests for denizens of Skyloft. Gratitude Crystals may be exchanged with Batreaux for several rewards. Humorously, Kukiel refers to them as "grabitude crackles."
Aside from the 65 Gratitude Crystals gained from aiding the denizens of The Sky with their problems, 15 more can be found scattered throughout Beedle's Island, the Pumpkin Landing, and Skyloft; however, they appear only at night. After the Goddess Sword is tempered with the Sacred Flames and becomes the Goddess Whitesword, Link is able to dowse for these scattered crystals once he has paid a visit to Batreaux.
Once 80 Gratitude Crystals have been found, Batreaux is transformed into a human and in his own gratitude rewards Link with the Tycoon Wallet, which can hold up to 9,000 Rupees. Furthermore, the transformations that Remlits undergo at night are undone as well, and enemies such as ChuChus and Keese no longer appear in Skyloft at night.

Gratitude Crystals resemble Star Bits from Super Mario Galaxy and Super Mario Galaxy 2. As characters from the Mario series have had cameo appearances in several past installments of the Legend of Zelda series, it is possible this was an intentional design choice.
Another possibility is that they are visually based on Star Fragments from The Legend of Zelda: Spirit Tracks. It is also possible that they could also be based on Force Gems, due to their propensity to appear when someone is grateful.
One likely explanation for the 16 Gratitude Crystals Link finds scattered around the sky, is that they were produced by a grateful person at some point in the past and left behind as most people cannot even perceive them. As a result, they where left behind presumably where they were originally formed. This is possibly demonstrated by the location of one of this 16 Gratitude Crystals, which can be found in the small cave where Link's Crimson Loftwing was imprisoned by Groose. It is possible that the Gratitude Crystal Link finds there was produced by his Crimson Loftwing upon being free from its confinement and reunited with its owner. Alternately, it could have been produced by Zelda's feeling of gratefulness that Link's Loftwing was unharmed and/or that Link could finally participate in the Wing Ceremony. Another possibility was it formed from Link's own feeling of gratefulness over reuniting with his beloved Loftwing.
Gratitude Crystals appear as a special type of Feast-based Food item for Companion Fairies, that are receive as a parting gift from Companion Fairies the player has parted ways with (which happens when a player has obtained Fairy while having the maximum number of Fairies). There are two Gratitude Crystals for each of the five elemental attributes and unlike other food items, they only come in Silver and Gold grades. Though they are called Gratitude Crystals, they do not resemble the Gratitude Crystals from Skyward Sword (instead they appear in the form of a Heart shaped crystal with Fairy wings) The color of the heart differs depending on the Crystal's element.
