A Shiny Twin

I waddled off the soft blanket and tapped right onto cold, smooth glass! Clack, clack. Then I stopped. Down inside the surface, another yellow face stared right back! Did it blink? I puffed my chest out wide to show I wasn't scared. The other duck puffed up too! I leaned my bill down to touch it—tap! Just cold glass. But underneath was a coaster with braided red cord, and my foot nudged it. We shared a shiny puddle that doesn't even splash!
