The Mystery Polluter
- Divine Beast Vah Naboris Main Quest
- Begin The Thunder Helm Side Quest
Speak to Dalia in the Northern corner of Gerudo Town to begin the quest.
Right next to Dalia is a waterfall. Climb up beside it (you cannot climb while actually in the waterfall) and you will see melon rinds floating down the water source.
Trace these all the way back to their origin (pretty much straight west) and talk to the Gerudo eating melons there. This Gerudo is named Calyban, and she rudely informs you that she will not stop eating Hydromelons.
Turn them in to Calyban, then return to Dalia to complete the quest for a Hydromelon. Dalia will then tell you to come back and visit her. If you do, there will be several harvestable Wildberry bushes.
Dalia has been working hard to start an orchard, but garbage keeps appearing in her water source, so her efforts are all for naught. What sort of vile polluter would toss his or her garbage away with such indifference?
Dalia planted the wildberries she received from Calyban and said that it's OK to pick them once they grow in.
With the source of the water pollution cleared up, all that's left to do is wait for the wildberries to grow.
