Nori

Nori is a reformed character in Barbie Fairytopia: Mermaidia. She is a mermaid who while rude at first, eventually agrees to join Elina in her mission to save Prince Nalu from Laverna and get the Immunity Berry. One of the obstacles is to prove your bravery by swimming through the Depths of Despair, an abyss in the middle of nowhere, that leads to the Mirror of the Mist, which will show Nalu's spot. In the process, sentinent vines trap Nori to prevent her from getting to the mirror, and Elina has to save her.
