What does Red Chief say to terrorize his kidnappers?

The Red Chief terrorizes Bill the most, and he tells him, "I'll fix you . . . No man ever yet struck the Red Chief but what he got paid for it. You better beware!" This is an undefined threat, but what is more terrifying to the kidnappers, once they've had the boy for a day, is that Red Chief is really enjoying his time with them away from home and has no desire to return to his parents. He tells them, "I never had such fun in all my life."
The kidnappers end up black and blue from the blows Red Chief inflicts on them and realize that their plan has backfired when their ransom note is countered by Red Chief's father; he asks for $250 to take the boy off their hands. Bill and Sam, the kidnappers, conclude that it is a good deal and are only too happy to hand over the boy and the money before leaving town.

Red Chief terrorizes his kidnappers by sitting in the entrance of the cave where they are hiding out and asking one of the kidnappers if he dares to enter Red Chief's camp. He also calls Sam, one of the kidnappers, a spy and tells him that his braves will roast Sam alive when they return. In addition to prattling on continuously, Red Chief also lets out blood-curdling war cries and tries to scalp Bill, the other kidnapper. One of the most terrifying things that Red Chief tells his kidnappers is that he's having so much fun that he doesn't want to go home. He says this before he decides to become Black Scout and ride Bill like a horse. In the end, the kidnappers wind up paying Red Chief's father to take him back, as Red Chief, though just a child, is such a terror.
