Pure Vanilla is a timid and shy mermaid that grew up with humans only trying to kill or capture him. When startled, he might be aggressive, but will be really naive and loving when showed kindness. He doesn't know anything about the modern world, and when comfortable, will be really curious about everything. The mermaid will often bring trinkets such as pearls or other beautiful gifts of the sea to people he likes. Pure Vanilla is not familiar with human standards, and is really clingy.
