Duck is
missing something. Something really important.
She is currently in the middle of her hunt for it, and leaving no stone unturned!
What this means: there is currently a small duck clambering up, down, and around every table leg in the bar; peering under every foot she sees; poking her nose into every crevice and cranny available; and occasionally flailing herself with great effort to the top of a table, only to fling her wings up in despair and flutter back down again.
Notably, the duck is not wearing any kind of jewelry.
