I am not sure how to add this information but I found this item in the seashell on the small island located in the middle of the "Sea Turtle Islands" which you can come to when taking a shortcut with Charles. "16:33 You have found a coral brooch." Maybe someone can help me in getting this info on the item page. Sibon 16:39, August 27, 2018 (UTC)
I added that info. Ideally, we should create a new page for that large seashell and for the island.
