Gillie Groats

Gillie Groats is a non-player character in the northern cow pen of Lumbridge, near the three dairy cows. She informs players how to get milk from a dairy cow. She also is an NPC that gives jobs to players. She is the daughter of Seth Groats, who is a farmer.

Her name is most likely a pun on "Billy Goats ", even though she is concerned with cows and not goats.
