The Puddle Pail

"You can't collect puddles!" Ernst and his big brother Sol set off for the beach one morning, pails in hand. Sol plans to fill his pail with shells, rocks, and feathers. But Ernst doesn't know what to collect. He'd like to collect dreamy, puffy clouds or faraway, twinkling stars. "You can't collect them!" Sol laughs. Then Ernst spots a colorful puddle, like a piece of sky on the ground. Now he knows what he wants to collect, but how do you collect puddles?
