Box of fluffies

When somebody asks you how you are, sometimes a Kiwi will reply "A box of fluffies, thanks". This is short for "a box of fluffy ducklings" which are generally thought to be cute, chirpy, full of energy and bloody glad they're not a chicken.  In other words, the Kiwi is telling you they are doing well or feeling good.  This is what fluffy ducklings look like.
