Listen for a ruffling sound. A ruffling cascade, like a stack of ladies' fans sliding silkily off a credenza. -- Gregory Maguire, Son of a Witch (2006) The ruffling sounds of a unicorn are reminiscent of: the feathers of a settling peacock a pillow being fluffed riffling through the pages of an enormous dictionary the rippling of a boat's sail the gentle shoveling of fresh popcorn into a bucket a breeze whispering through leafy treetops or a field of grass on a mild summer's day a pigeon fidgeting on a windowsill a bedsheet being shaken The waveform of a unicorn's ruffling sound.
