Grimesquit Grime[1] is a somewhat crazed woman found in Varrock Sewers, with her sister, Phingspet. Both she and her sister can be found near ladder to east Varrock. Grimesquit and her sister help the player to train their cat by catching eight rats during the Ratcatchersquest. After this is accomplished, they will redirect the player to Jimmy Dazzler.
During the first interactions with the player, they speak in a unique dialect, a mixture of British English and gibberish. However, towards the end of the quest, this is revealed to be a ruse pulled off by the two sisters as a joke.
