Hestu

Hestu is a character that appears in The Legend of Zelda: Breath of the Wild. He is a large Korok who happens to be the most celebrated musician of Korok Village.

Link can meet him for the first time on the road in west Necluda that leads to Kakariko Village. He claims to be lost and wants to travel home to Korok Forest where his 'Grandfather' is. Later in the game this is revealed to be the Great Deku Tree. Speaking to Hestu in West Necluda will activate "The Priceless Maracas" side-quest. There is a nearby Bokoblin camp from which you gain the item "Hestu's Maracas" Give them to him and from there on, he can be paid in Korok seeds, which in turn he will expand your shield, sword, or bow inventories.

After paying him twice for inventory upgrades, he will then move north to the 3 stables along Hylia River (to follow the river north, as his grandpa told him to). These include: just northeast of the Riverside Stable (north of the Owlan Bridge), just southwest of the Wetlands Stable (northeast of the Bottomless Swamp), and just south of the Woodland Stable (west of Pico Pond).

After paying him six more times for inventory upgrades, he will then move to his final location in Korok Village, where he will remain for the remainder of the game to trade Korok seeds for inventory upgrades.
