Why does huck ignore Jim's waring?

Huck is thrilled with all the things they managed to get from the house and tells Jim that he wishes they could have fun like that more often. Huck is also still curious about the man in the house but Jim refuses to talk about him. Huck mentions that he thought they would have bad luck after he brought a snakeskin into the cave, not great luck like what they were having. Always superstitious, Jim warns Huck that the bad luck is still coming.
