The Hateno Bay is a location found in Breath of the Wild.
The bay is part of the greater Necluda Sea and it located southeast of the Hateno Ancient Tech Lab right alongside the Hateno Beach. As with most of the coastline of the Necluda Sea, there are Blue Lizalfos swimming around in the water, as well as some Water Octoroks.
At the southeast part of the bay, right where it meets up with the adjacent Deepback Bay, there is a yellow flower. After collecting a series of flowers, it leads to a white flower on one of the rocks out in the sea, which causes a Korok to appear. Right next to where the large rock with the Korok is located, there is a treasure chest in the water. Pull it up with Magnesis and open it to get a Purple Rupee.

These sheep are at the Hateno Beach, right alongside the Hateno Bay. There is a large Moblin camp here, with dangerous Blue Moblin and Black Bokoblin. Defeating all of the enemies at the camp and then returning and speaking with Koyin will complete the quest. The camp also has a treasure chest that contains a Ruby gem.
