Molly

Molly is a mermaid who lives in King Neptune's castle at the bottom of the sea. It is unknown if she is a member of royalty, as she states that 'we all' live in his castle, which may mean that it is the home of a large group of mermaids, possibly all the ones that exist within the show's reality.

Personality
Molly can be quite sensitive, as shown when she couldn't find Swish the Seahorse, but she is knowledgeable about the sea around her home and has been shown to be courageous and resourceful.

Appearance
Molly is depicted as many different forms of household waste put together to form the shape of a mermaid with yellow skin on her human half and pink skin on her fish half. She has pink hair, pink gloves, a pink tail, a bra made of two light brown shells, a brown belt with white frills and a light brown hennin with pink ribbons.
