The Mystery Polluter

The Mystery Polluter is a Side Quest in.

Overview
This Side Quest is one of four Quests needed to complete in order to help the people of Gerudo Town and receive the Thunder Helm from Riju in "The Thunder Helm" Side Quest. Link can begin this Quest by speaking to the crying Gerudo child, Dalia, in an empty area near The Noble Canteen in Gerudo Town. She is crying because she wanted to plant a fruit orchard there, but the water from the nearby water trough is unusable due to a flow of trash in it. After she is finished speaking, Link will receive the Quest and must investigate the water trough. Link will find Hydromelon rinds flowing down into the trough through the upper waterway and must follow where they are coming from to find the source of the pollution. This leads Link to a Gerudo woman named Calyban, who is sitting on the walls of Gerudo Town eating Hydromelons and throwing the rinds into the waterway. When Link talks to Calyban, she rudely insists that she can do what she wants. Stating that altruism is for suckers, Calyban refuses to stop eating melons unless Link brings her a 10 Wildberries. Wildberries are often found in cold places, such as the Gerudo Highlands and Hebra Mountain.

Once Link has collected 10 Wildberries and returns to give them to Calyban, she is amazed at how delicious they are. Calyban says that she may stop eating other fruit entirely if she has Wildberries. She then realizes how selfish she's been and leaves to go help Dalia clean up the melon rinds. When Link returns to Dalia, Calyban has already cleaned up her trash and left. Dalia gives Link from a Hydromelon that was given to her by "the lady who cleaned it up" as a thank you for caring about her. Dalia says that she also gave her some Wildberries, so Dalia decides that she is going to grow a Wildberry patch there. She tells Link he can come eat the Wildberries anytime he likes and the Quest will be complete. Just as Dalia says, Link can come back later to find that three Wildberry plants have grown there. After the Quest, Link can find Calyban sitting in the shade nearby with Hydromelons and Hydromelon rinds. She says that she gave the Wildberries to Dalia to apologize and because she will always prefer Hydromelons.
