Mermaid is, as her name describes, a beautiful mermaid who Little Bear occasionally meets when he goes to the lake. She’s friendly and takes him to see places underwater.
Her first appearance was in the episode "Little Bear's Bath".
She has long teal hair with a purple flower in it, golden seashell earrings, lavender skin and purple lipstick.
- The majority of Little Bear's friends never got to see Mermaid and were dismissive whenever Little Bear tried to tell them about her. However, in "Little Bear and the Sea Monster", Owl got to see her. Emily also got to see her in "Granny's Old Flying Rug".
- In Little Bear's Mermaid, Little Bear and his friends pretended to be asleep, because they wanted Mermaid to show up, so they can see her.
