Karen Castle

Karen's Castle and her servants

The Antarctic Ocean Castle is the home of the Mermaid Princess, Karen, and her servants. The castle only appeared once, in episode 27 during a flashback.


Karen's Kingdom is at the South Pole. After defeating Gaito, Karen returns to her kingdom to rebuild it along with the mermaids.

During the short scene where the castle is pictured, only the throne room is shown onscreen. It consists of a throne, multiple columns, and purple ice crystals. The walls and floor are purple as well. Karen's throne is a large clam shell, resembling the Mermaid Princesses' necklaces.
