when sharks croak heh

This evening after I put the little heathens to bed, I was cleaning the kitchen. The windows were still open, and the frogs were croaking. Loud enough to hear them inside. I was thinking happy spring thoughts until Fang ran into the kitchen with, "Shh! Hear it. I scared".

"Go back to bed." I said.

Shaking his head he said, "I scared."

"Scared of what?"

"Hear it?" he whispered loudly. Then he nodded and said, "Sharks!"
