Aquamarine Cookie (글라스마린 쿠키, gullasumalin kuki, "Glass Marine Cookie") is a Guest Cookie released in the second part of the A Mermaid's Tale update (v4.10), appearing first as a NPC in A Mermaid's Tale Special Episode. Aquamarine Cookie is the gentle and sweet sister of the Gem Mermaids Black Pearl Cookie, Crimson Coral Cookie, Gold Citrine Cookie, and Mystic Opal Cookie, residing in Tearcrown. She is a plant and gardening enthusiast.
If you ever find yourself around the grove of delicate, water-hued corals, Aquamarine Cookie will surely come to greet you with a smile as bright as her gem. The Gem Mermaid worked tirelessly, directing currents and nurturing her plants to create a colorful flower garden on the sea floor. Aquamarine Cookie's eyes fill with warmth whenever a gentle leaf of kelp touches her hand. She embodies the idea that tender kindness is one of the forces that keep the kingdom safe.
