Marina's littlest sister is called Sirene. She is a very smart little mermaid and loves plants. She has a whole garden deep in the lagoon that she tends to and grows all kinds of wonderful things to eat. Sirene has her garden all organized in rows, and gets a little grumpy if Marina or Coral go in there, but she is very happy to share any and all of the things she grows after she picks them! Sirene also loves to sing, and enjoys a good puzzle.
