Nestling

Pickle-Pee is a character in Dark Souls III.

Location
Pickle Pee can be found in Firelink Shrine, along the rafters located above the shrine.

To access her, the player must first purchase the Tower Key from the Shrine Handmaid for 20,000 souls. After accessing the tower behind the shrine, the player must drop at the middle of a partially crumbled bridge and onto the roof. From there, Pickle Pee can be accessed either at her nest, or directly below it by entering through a small hole on the front of the roof and then walking along the rafters above the shrine.

Trivia

 * Pump-a-rum stands for "bumpy and rough", in a similar way as other birds in the series have asked for items like "warm and soft" and "smooth and silky".
