Location: This quest can be found in Lonalulu.
Objective: Obtain a Dulcet Dulse to Help Soothe the Mermaid’s Sore Throat
To obtain the Dulcet Dulse, travel to Sniflhiem then sail to the lone island located to the southeast. Dock there (its name should be the Insula Algarum) and head forward until you reach a bridge with a yellow fish man fishing there. Talk with him to get the Dulcet Dulse, then return to Lonalulu. Head back to the boy and give the dulcet to the mermaid in the water near him. When that is done, talk to the boy to complete the quest.
Reward: 5 Molten Globules
