The specific problems are: Check about the range for the price of the potions from the Mermaid Treasure Shop. Need images of the tails by themselves as PNG files that follow the Image Guidelines and clearer images of the potions. Double check about the "oldest tails" section and the icon for the "Queen Harmony Mermaid Potion".

Mermaid and merman tails are accessories that used to be available in the Royale High shop. They could be purchased with Diamonds. The only difference between mermaid and merman tails is that the merman tails don't have a seashell bra on the chest. Mermaid and merman tails were removed on November 6, 2019 due to the release of the new shop, but can still be used if already bought. You cannot trade these items.
On September 19, 2025, mermaid tails returned with a new look and obtainment method. After the player looked for a mysterious bottle by the ocean on Campus 4 and completed the questline associated with it, the "Mermaid Treasure Shop" would unlock. The shop allowed players to purchase a variety of potions for mermaid tails, along with other items. The only exception to this is the Goddess Of Triumph 🎗️ Sea Of Strength Mermaid Potion.

Note: Mermaid Potions that are purchasable in the Mermaid Treasure Shop have a randomized price range per person per day. Prices listed next to the item are an estimated range.

Unobtainable Tails[]
The mermaid and merman tails were purchasable tails that the player could obtain prior to the November 6, 2019 update. Accounts that purchased these tails prior to the update can still equip them in their inventory.
Merman tails are exactly the same, minus the seashells.
