"There ought to be lots of frogs now," said Bunny.
"Yes," agreed Sue. "I hear them singing every night."
"Frogs don't sing!" her brother said.
"Yes they do too!"
"No they don't!"
"Then what do they do?" Sue wanted to know.
"They croak!" said Bunny. "Frogs can't sing, they just croak."
"Well, they can hop then!" Sue was sure of that. "'Cause the ones George Watson let loose at our party hopped."
"Oh, yes, frogs can hop," Bunny knew that well enough.
"All 'ceptin' pollywoggles," went on Sue. "They jest wiggle."
