A goblin who lives in the Forbidden Forest
During their first year, the Slytherins attacked Nibgit while he was cooking in the Forbidden Forest. They were looking for Rachel Etham, who had been taken that night.
Near the beginning of their third year, the Slytherins encountered Nibgit at the old inn (The Good Inn) in the ruined portion of Old Hogsmeade. He was leaving his “magical pantry,” a cave where food stored inside does not rot.
