Hestu
Hestu is a Korok who features in The Legend of Zelda: Breath of the Wild. He will help Link increase his weapon inventory space in exchange for Korok seeds.
Hestu is a Korok, and a musician from the Korok Forest. When Link meets Hestu for the first time, he has lost his maracas and asks the player to find them for him. Completing this quest ('The Priceless Maracas'), allows the player to exchange Korok seeds for an increased slot to their weapon stash, bow stash or shield stash inventory space. Each pouch can be upgraded a total of twenty four times.
Hestu is first found south of Kakariko Village and moves location after expanding the players inventory twice.
