You get Bottle of Vintage Wine, 2 Cork Boots, 82 Gemstones, Sidereal Bag, Torn Red Cloak, and Worn Dagger!

You put the items inside the newfound sidereal bag, and tell Moonflower that you'd like to share them with the rest of treasure-hunting party.

Moonflower: "Ooh, good call! Bet they're gonna be super stoked!"

After rejoining Furia Storm up the ramp, you exit the cave and make your way across the beach once more.

You soon find yourselves back in the streets of Amblerta, where the townsponies have returned about their business. Once Aqua Skies and Marine Wave’s house comes into view, you see Sea Swirl running outside to greet you, followed by Dawn Break and Sweet Biscuit.

Sea Swirl: "There you are! See, girls? I told you there was nothing to worry about."

Sweet Biscuit: "That's what you say now. Huh... and who's this? She looks familiar."

You recount what happened to your friends since you last met, and offer to split the treasure with them.

Sea Swirl: "No way! Well, if you insist, this cape would look pretty awesome with my Whirlpool cosp— I mean, Nightmare Night costume."

Sweet Biscuit: "That's a cape? It has more holes than fabric. The boots are kind of cute, though."

Dawn Break: "I don't think I've ever seen wine this old. Good find, but I'd feel bad taking it from you, so why don't you three pick first? From what I've heard, you deserve it."

Furia Storm: "Pass. If I wanted something, I would have taken it a long time ago."
