Fairy Fountain: Desert Sands

is a side quest in.

Overview
This side quest is considered the last of the Fairy Fountain quests, after Fairy Fountain: Grassy Plains and Fairy Fountain: Deep Snows, although the side quests can be completed in any order.

This side quest has a time limit of 13:00 minutes. It first starts with the shadowed figure asking the character to bring 600 rupees by getting them from the Yiga Clan.

The Yiga Footsoldiers will only drop a Green Rupee(worth 1 rupee), while the Yiga Blademasters drop a Purple Rupee(worth 50 rupees). After this, a Blue Moblin must be defeated in order to open a gate, and then a Stone Talus to make more Yiga spawn.

Once the targeted position is reached, the shadowed figure takes all the rupees collected, and will reveal herself as the Great Fairy Tera. Once defeated, if this was the character's first try, then he/she will get 1 Ethereal Stone, 3 Fairies, 10 Raw Whole Bird, and 500 rupees.

If all of the Fairy Fountain quests are completed, then the character will be able to do Fairy Fountain: Battlefield
