Fountain of Happiness
From Zeldapedia, The Legend of Zelda wiki
The Fountain of Happiness is a location in the The Legend of Zelda: A Link to the Past. It is at the center of Lake Hylia, and it houses Venus, the Queen of all Faeries. Link can throw Rupees into the fountain. Once he throws 100 Rupees in, Venus will appear and award Link either a Bomb or an Arrow upgrade. There are seven total upgrades for Bombs and Arrows. The first six increase capacity by five, and the last one increases capacity by ten. There is also a Faerie Fountain which can be accessed by bombing the crack in the east wall.
