What religion is Huckleberry Finn?

Excuse me, but I believe there might be a misunderstanding in the question. Huckleberry Finn is a fictional character created by Mark Twain in his novel Adventures of Huckleberry Finn. Being a fictional character, he does not have a real-life religion associated with him. The novel focuses on themes such as freedom, slavery, and morality, rather than religious beliefs. Could you perhaps clarify your question or provide more context?
