Bat Burps

Zion just polished off some chocolate milk as he was sitting beside me, then gave a small belch.  "That was a bat burp, Mom," he said seriously.  "That's what bats do when they get some air inside them."  He hopped along behind me, following me into the dining room.  "Do you think another name for bats is 'flappies'?" He flapped his arms like bat wings and nodded to himself.  "Yes, that is another name - 'flappies'." He hopped busily off leaving me to furrow my forehead in confusion as to where all the bat love came from randomly.
