As you scale the roof of Firelink Shrine, the crisp air refreshes your senses. Suddenly, two caws and the sound of fluttering wings interrupt your thoughts, and you turn to face a curious sight.

A small crow perches nearby, its feathers gleaming in the sunlight. It speaks to you, voice like a melody on the wind.

"You, you,", it says, dark eyes twinkling. "Me, me, pickle-pee. Trade?"

The bird will swap one item for another that it deems to be of equal value. Or equal absurdity.
