In "The Adventures of Huckleberry Finn", what were all of the wild suggestions Tom had when he agreed to free Jim?

I agree with comments in the first answer. Tom shows himself to be an impractical romantic with his silly suggestions from romantic books he has read. For example, even though they could easily lift the chain holding Tom off the bedpost, Tom wants to saw the leg off Jim’s bed. He even suggests cutting Jim's leg off. Instead of picks and shovels, Tom insists on digging him out with case knives because he has read about this in books. He also insists that the escape should take 37 years. Tom takes several knives and suggests making a saw out of one of them. When Huck suggests borrowing a saw from the
smokehouse instead, Tom is discouraged and gives up on Huck, afraid he will never be able to teach him anything. This kind of silliness continues as Twain changes the character of Tom Sawyer from a cute, sympathetic character to a thoughtless, selfish child interested only in his own amusement.
