What religion is kelp?

Excuse me, could you please clarify something for me? I've come across a rather puzzling question, and I'm not quite sure how to answer it. The question is: "What religion is kelp?" I'm a bit confused because kelp, as I understand, is a type of seaweed, a plant that grows in marine environments. It's used in various culinary dishes and even has some nutritional benefits. But religion, on the other hand, refers to a set of beliefs and practices followed by a group of people. So, how can a plant like kelp have a religion? Could you possibly explain this to me? Thank you in advance for your assistance.
