What it is like
Marshmallows tumble down from a floating pink cloud into a blue lake, and little ducks in leaf hats paddle about saying mallow, mallow, mallow.
Marshmallows are very shy at night. To catch one you must be softer than soft: like a bedtime hug, like a sleepy yawn, like a blanket saying goodnight.

Catch a Marshmallow
Softer than soft, or it bounces away
