After clearing the Water Mine in Coral Island, Gorm the giant will want you to bring him a Royal Grape Blazer. This comes as part of the Disguise Wanted quest, where Gorm wants to be with the humans but needs a disguise. This quest will also require you to find him a flower, wool, and Round Stylish Glasses, but the hardest item to find is the Royal Grape Blazer. The reason is that there are multiple prerequisites before you can buy this blazer. Here’s where you can find the Royal Grape Blazer in Coral Island.
The Royal Grape Blazer can be purchased from the White Flamingo clothing store in Coral Island, but you need to reach Town Rank D first. The Town Rank starts at F when you arrive, but there are plenty of ways to increase it. That can be done by donating to the museum, completing offerings, and healing coral sites. You can check your progress in the Town Rank section of the menu.
Once you reach Town Rank D the Royal Grape Blazer can be purchased for $2,700, but there is one other catch. White Flamingo’s inventory rotates on a daily basis. We aren’t sure if this is consistent for everyone, but it was in-stock on a Tuesday for us. You will need to check back daily to see if it is in-stock. The image for it is a blazer-hoodie combination, with the hoodie being purple.
The Royal Grape Blazer also has a chance to appear in Ben’s Caravan, located at the northern tip of town. However, his stock is random, so there is no way to guarantee he will have it in stock. Once purchased, bring it along with the other items to Gorm in the Giant Village, located west of your farm.
