Fingernail

A Fingernail is an item in Pathologic 2. They can be given to the Ferryman to travel across the Town. They can be traded for from Catnip, Chickadees, Finches, Siskins, Swifts, Teensies, and Tots, and traded to Geese and Starlings, as well as to the Dead Item Shop. They can also be randomly found from opening packages or looted from containers.

Worms require one Fingernail to ferry the Haruspex at the start of Pathologic 2. This increases to two starting from Day 7. It is said that ferrymen line the boats with fingernails to make their path smoother. The Gorkhon is a kind, but dangerous river, so ferrymen need fingernails to ensure they can always return.
