Huck Finn satire essay topics?

I have to write an analytical essay about Huckleberry Finn. And I am having a reeeeally hard time coming up with a topic. I have considered writing about the gullibility of people that are in the novel and how that ties into religion about how people believe everything the Bible says without thinking about it. My teacher also said he wants us to talk about how Huck's voice is satirical in our respective topics because he said it's inevitable to mention it. I don't know how to integrate that in my essay topic though. So if anyone can help or give suggestions or provide quotes that would be much appreciated. Thank youuuu.
