Grimesquit Grime is a strange woman who loves hunting rats. She has a sister, Phingspet. Grimesquit and Phingspet help the player during the Rat Catchers quest. They can be found in the Varrock Sewers. Grimesquit speaks in a rather odd language, a combination of gibberish and English, but this is later shown to be a joke on the player.
The player must catch eight rats for her and her sister using their cat. When Grimesquit and Phingspet find that you have caught all the necessary rats they will tell you about Jimmy Dazzler.
In the Varrock Census of Year 160 (Fifth Age), her occupation is listed as "profession withheld".
- She has a gravestone in the New Varrock graveyard which reads, "Grimesquit. Killed by the dreaded Feline Flu."
