Little merboy who sings
Eau is a cheerful person and kindhearted. When the ocean is polluted and get filthy, he gets angry and does anything to clean it because of his OCD for cleanliness. He is still little, so he is very social, but because of his voice sounding like a little girl's, the others usually don't talk to him.
A pocket Knife Eau found when he was cleaning around the coral reefs.
Eau was born in the ocean by Tethys Island. He loves to swim with the fish and the other aquatic animals. His father swam away after he was born and his mother died in a oil spill when he was 7. He wouldn't let anybody take him in, he wanted to be alone. After the death, he was and is determined to clean the ocean by any means necessary. He has a little angel fish that follows him around, he named her Luna.
