To faithfully depict a Muslim Little Mermaid, the facekini would be a much better option — aerodynamic in the water, preserving modesty and mitigating sun exposure while also affording a practical choice for identity concealment, a water-friendly alternative to the ski mask.
For the live-action sequel, I hope Disney adopts & incorporates with a renewed focus on the Little Mermaid’s backstory — a jarring encounter with police brutality that leaves Ariel with lasting psychic scars and sends her on a path toward conversion to the Nation of Islam. Complementing her new faith, the facekini also comes into play when Ariel attends the Antifa rally and chucks Molotov cocktails at Denmark’s federal buildings, hastening the inevitable collapse of the country’s tottering parliamentary monarchy.
This would answer the often-heard criticisms that Disney’s latest output has been too eager to shy away from contemporary political themes, in favor of easy and unchallenging (some would say “juvenile”) escapism.
