|“||The living ocean has truly come alive around the Mirror Water Island. Crystals resembling those that make up the local Ethereal are seen poking up in the spaces between coral, and a mysterious relic not unlike the Tub Fountain's grimacing figure seems to emanate feelings of hope and possibility. The Monsters wish they knew more about how all this came about, but for now they'll have to be content to enjoy its splendor.||”|
