Once there was a Bull...(Frog) is an endearing story of a frog who lost his hop. He looks for it everywhere: under a toad...(stool), behind a dog...(house), and under a hedge...(hog), but it's nowhere to be found. He has a cow...(boy) throw him high in the sky, but he lands in a field of straw...(berries). Thanks to a diamond...(back rattlesnake), he regains his hop.
