The North Pacific Ocean Mermaids live in the North Pacific Ocean Castle. Their princess and ruler is Lucia. They only made an appearance in Episode 1 and Episode 13 of Mermaid Melody Pichi Pichi Pitch.
The Mermaids seem to care a lot about their princess, so they get a bit anxious when Lucia decides to leave them to go and search for Kaito. They also line up in a perfect straight line when Hippo walks past, and this shows their respect towards him too.
The Mermaids have different colored hair and the rest of their outfit is pink. Some mermaids have more darker pink tails and others have more lighter pink ones.
List of Mermaids
The Mermaids have to communicate to Mermaids from other kingdoms. In order to do this, they have to use dolphins such as Momo.
Lucia's role is to make sure that every mermaid living in her kingdom is safe and to forfill her duties.
