Hawk Grass

Hawk Grass appears in Twilight Princess, and is blown into to summon a hawk, which Link can use to solve certain puzzles. In Ordon Village, it is nessacery to use this grass to get Uli's crib back from a monkey. On Lake Hylia, Link can use it to summon Plumm, a Myna Bird, to play his minigame, which he can only do as a wolf. When Lanayru Province was covered by twilight, Wolf Link can howl to mimic the grass, which summons a Twilit Kargarok, which he uses to access upper Zora's River.
