Minnie and Moo: Hooves of Fire

It's a perfect day for the First Annual Hoot, Holler, and Moo Talent Festival.
The sun is shining in a warm autumn sky and the stage is set. Mr. and Mrs. Farmer are away on vacation, Minnie and Moo are dressed in their togas, Elvis has his bagpipe, the hyenas their jokes, the fox his magic tricks, the sheep a protest poem, and the cash box is stuffed with money from ticket sales. A perfect day.
Wait a minute … Where is the cash box? Why are those coyotes on motorcycles? And who pushed those Porta Potties down the hill?
