TLoZ: A Link Between Worlds has a sidequest where you find 100 little cute hermit crab octorok things. Most of them are well-hidden in trees and under rocks and such, and can only be found by listening for their plaintive squeaking cry, which makes headphones a must. Fortunately, the music of that game is essentially A Link to the Past: Symphonic Suite.
Oh, and Mother 3, duh.
