The Private Oasis was a temporary lobby realm created during August 2018 so that players could load in their inventory faster for the new Earth update so that it could prevent data issues from occurring. The original Earth replaced it as the lobby on September 13th, 2018.
This realm was smaller and had very few players per server. It resembled the old Diamond Beach, however many buildings and features were taken out. Some diamonds were scattered around the realm. The map had many tropical elements such as a volcano located nearby and a lighthouse that radiated light through the starry skies.
Players were able to teleport to Royale High, Fantasia Getaway Resort, or Enchantix High through caves (rather than castles, which added to lag) and the carriage. Players could also jump higher.
Mermaid Pool[]

The Mermaid Pool
After Earth replaced the Private Oasis as the lobby, a smaller version was created called the Mermaid Pool, accessible through a small portal near the café. It was much smaller than what it used to be and was used for the same purpose as before, though only holds a single player per realm. It was later removed when Divinia replaced Earth in 2019, not returning with the 2019 version of Earth when it was added back in August of that year.
Nature Noises[]
In this realm no music was played, there were only nature noises. The Private Oasis and the Royale High 2017 lobby are the only realms which didn't have any music.
