I like the Troll Keel story...
We liked it too when we read it. Ought to be a different version for the Lee and Weather Helm Troll, but I'm not a smart enough children's writer to work it up.
My wife has an uncle who liked to distract a kid and then put a small fish on his line. Then he would call the child back to pull in the fish. Really had a great time, with the kid and then telling the parents after. Went a little sideways with our boy. He made uncle clean and aunt fry it up for him. After all, he caught it.
