Once upon a time, there was a little robot named Tracto who lived in a world full of puzzles and mazes. Tracto was very tractable and could easily solve any unary problems that came his way.

One day, Tracto was faced with a new challenge, an undecidable maze. No matter how hard he tried, Tracto just couldn't find his way through the undirected maze. He tried every possible solution but nothing seemed to work.

Just when Tracto was about to give up, he remembered a wise old saying, "If at first you don't succeed, try, try again." And so, Tracto tried again and again, never giving up until he finally found his way out of the maze.

From that day on, Tracto was known as the little robot who never gave up. He continued to solve puzzles and mazes and always found a way to be tractable, even in the face of undecidable challenges.

The End.
