(Just some random idea that popped into my head ._. Note, my actual Ninjago OC is NOT A MERMAID!!! That would end up making her a Mary-Sue character, so this is just a random idea, so please don't say that Allura [my oc] is a Mary-sue character) Allura, a mermaid living in the enchanted oceans of Ninjago, wants to become a human to be reunited with the boy that she met long ago, was given permission by her mom to go there. However, Serene, her older sister and a sea witch, gets angry at her, and plots her revenge to make her turn into sea foam so she can never see the ninja again. (Yeah that's all I got ._.)
