I have something that might interest you. Would you like to hear it?
1) Sure. What is it?

Did you know the longest waterway in Maple World is the route that connects Aquarium to Herb Town. Today, we can travel via the Dolphin Taxi, but that was once a life-threatening route. Around the border between Mu Lung Garden and El Nath Mts, there is an area that's surrounded by fog all year long. It's known as the Sea of Fog.
1) What's the Sea of Fog like?

It's a place where the current is unpredictable and a thick fog blinds you. The place is surrounded in a mystique of frequent wrecks and countless terrifying rumors.
1) What sort of rumors?

This is the most famous one: Once, there was a time when pirates roamed the seas, threatening Maple World. One nameless but courageous navy admiral hunted them all down. His fleet was undefeated, until one day it vanished into thin air. Decades later, his fleet reappeared in the Sea of Fog as a ghost ship.
1) Eek! A ghost ship?

Har har. It's only a rumor among sailors. I, myself, have yet to see it. But I thought you'd be interested. Say, how would you like to investigate the ghost ship of the Sea of Fog?

Great! But I don't have any clues for you. Oh, actually, maybe the Dolphin Taxi could tell you something useful. It passes by the Sea of Fog every day. Who knows, maybe the ghost ship really exists!

Har har, you're only human, I suppose. Anyone would be scared after hearing the story. Right?

Be careful out there. The admiral's rage continues to rock the ship to this day.

Have you met the Dolphin Taxi? You might need its help to get to the Sea of Fog.
