In addition to generic uses on many amiibo-compatible games, the Wolf Link amiibo unlocks costumes or artwork in several games. It also has a few noteworthy uses: In Legend of Zelda: Twilight Princess HD, scanning the amiibo unlocks the new Cave of Shadows dungeon. In Legend of Zelda: Breath of the Wild for Wii U and Switch, scanning the Wolf Link amiibo summons Wolf Link as an ally that assists Link in both hunting and fighting. However, his default health is only three hearts and he has low defense. His health can be increased by clearing at least one section of the Cave Shadows on Twilight Princess HD and saving data to the amiibo. In Animal Crossing: New Leaf, scanning the Wolf Link amiibo summons Wolf Link as a villager that can move into your town.
