Siren Tail

The Siren Tail was handed out as an apology. According to the wiki, the developers released it after delaying the Summer Quest update, and you got it by placing well during the MERMAIDS! Special Rounds. It was added on July 5, 2025 in Summer 2025 and filed in the Closet under Achievements.

The wiki adds that it became unobtainable once the Takeover Event released, so the Special Round route is no longer the way in. The page itself still lists the item as available, which makes it worth checking in the game.

As an Accessory (subcategory Tail) for female avatars, it has four colour parts: Tail, Bottom Fin, Details and Wings. Its toggles come in two groups, Default and Queen, and each one switches the wings on or off.
