Mermaid Island is a tiny island located between Pelican Town and the Fern Islands. You can get there after unlocking Willy’s boat (the one used to get to Ginger Island); a ticket to Mermaid Island costs 200g.

Willy’s boat can now take you there. The tutorial can be found here, but beware of spoilers:

You will meet the Madam, who owns a bait shop on the island. There is also a refreshment stand on the island, which is home to the lovely Ice Fox.

Tropical fish can be found in this location, and it even has its own Epic Fish (install more new fish mod for that). Furthermore, the Island contains new forgeable items such as fruit and starfish.

Summer Market – This market features shops selling new trees, crafts, and recipes, and it is held every summer on the 15th and 16th.
