Great Dragonfly Fairy

Quote from The Legend of Zelda: The Minish Cap Great Dragonfly Fairy figurine:

"The Great Dragonfly Fairy of Royal Valley. She gives you a larger quiver, allowing you to carry more arrows with you."

The Great Dragonfly Fairy is found in the Royal Valley. The first time encountering her, she will ask Link five questions. After answering all of the questions right, she will reward Link with a larger quiver. Like most Fairies, she will replenish low health upon subsequent visits.
