A researcher from Broadleaf has come to investigate how the water remains so pure in order to solve the pollution problem contaminating Sequoia Valley. In order to help with this, he wants you to secure three water samples from around the area. All three samples can be gathered from the southeastern portion of the city, with big markers showing exactly where to go; you will see blue sparkles at each location. The only tricky one on the map is the one at the base of the tower with the stairs.
Bring the water samples back to the researcher, who now wants you to fetch another sample. This time, you will be going to a small island just east of Makronos. If you land with your airship, there will be a short scene and then a monster shows up. Defeat the level 69 Jolly Jelly, which is just a normal monster, after which you’ll automatically collect the water sample. Return to the researcher with the water sample to finish the quest.
