Thumpety-Thump on a Treasure Hunt

The small-time con man, Thumpety-Thump, happens to have the other half of the treasure map that the ruthless Boss needs. The latter tricks the main character into taking it. Later, Thumpety-Thump gets in more serious trouble, because he is relentlessly followed by a caterpillar named Chatterbox, and later they are joined by the mantis Braineater as well.
