Tom and Plans

So Huck and Tom know where Jim is but what complicates things is that Tom isn't fine with breaking Jim out the easy way. Tom comes up with these crazy ideas about having Jim dig his way to China or make a moat around his cabin or have him tame a rattlesnake but it never ocurs to Tom that doing things the easy way makes things a whole lot easier. What would seem easy to me is to finish digging the hole they were digging and  get Jim out, take the raft and head down river. It's either I missed something or they don't do the plain and simple.
