Gratitude Crystals

    
                               

Batreaux, the demon who lives behind the waterfall cave in Skyloft, wants to become human. Gratitude Crystals are the key. They're the thanks of the people you help. There are 80 in all: 65 from twelve sidequests (five each, plus an extra five on one of them), and 15 loose crystals that only appear around Skyloft at night.

Batreaux's Rewards

  • 5 crystals: Medium Wallet (holds 500 Rupees).
  • 10 crystals: a Piece of Heart.
  • 30 crystals: Big Wallet (holds 1,000 Rupees) and the Cursed Medal.
  • 40 crystals: a Gold Rupee.
  • 50 crystals: Giant Wallet (holds 5,000 Rupees).
  • 70 crystals: two Gold Rupees.
  • 80 crystals: Tycoon Wallet (holds 9,000 Rupees), and Batreaux finally becomes human.

Loose Crystals

The 15 loose crystals only appear at night, so sleep in a bed until dark first. Twelve are scattered around Skyloft, two are on Pumpkin Landing and one is on Beedle's Island. Look on rooftops and ledges, around the waterfall and on the roof of the Knight Academy.
