Biography
When Link encounters a Korok, it believes it has been found by Hestu before realizing that Link is not Hestu. The Korok will then give Link a Korok Seed, asking him to return it to Hestu.

Upon finding Hestu, Link will discover that his Maracas were stolen from him by his fellow Koroks as part of a prank. Talking to him will trigger The Priceless Maracas Side Quest, in which Link will have to retrieve his Maracas from a chest in a nearby enemy camp. Once he returns his Maracas to him, Hestu will find out that the Korok Seeds inside the Maracas are gone. Hestu will then tell Link that if Hestu had a Korok Seed, he would be able to sing, dance and use his powers to expand Link's Inventory. Hestu can upgrade Link's Weapon Stash, Bow Stash, or Shield Stash.

Hestu will only allow Link to upgrade a few times before announcing that he needs to get back to Korok Forest. However, he gets lost on the way, and can be found facing Wahgo Katta Shrine north of Riverside Stable, behind the Wetland Stable or in front of the Woodland Stable. He allows Link to get several more upgrades before remembering the way back to Korok Forest and leaving again.

Nomenclature
Hestu may come from the word heath, which is a word for untended land where certain flowering shrubs grow.
