When the kids fight over a coin for ice cream, J. Field Mouse tells his grandchildren the story of a mouse whose greed and dishonesty became his undoing. Feigning blindness and playing the fiddle, he collects enough money to live an opulent lifestyle. His home, marked by a shabby exterior, turns out to be a mansion where he lives it up with his riches. All the fiddler's luxury is in jeopardy when the tax assessor knocks on the door. The fiddler hurriedly presses a series of buttons to hide his opulence and make his home look like a hovel. He succeeds in confusing the tax assessor to the point that he flees in frustration, but an eavesdropping cat plays on the fiddler's greed and lures him into his jaws by placing a gold coin there. And that, says J. Field Mouse to his grandchildren, was the end of the greedy mouse. One of the grandchildren asked if the greedy mouse got eaten. The grandfather said, "Yes, he ate him all up,". But one of his grandchildren notices a gold (cat's?) tooth hanging on display and realizes that things weren't quite what they seem.
What happened to the tax assessor and his dog?
The tax assessor leaves after being confused by the fiddler, who changes his home into a hovel. There is no dog in this story, however, but it does mention a mouse and a cat.
