Brawler Tiny is a GoblinBrawler in the Goblin Camp in Act One. She is hanging around the eastern courtyard, listening to Novice Crusher boasting. As a member of his entourage, she will join on Crusher's side if you choose to fight him.
Once the interaction with the egoistical goblin is over, Tiny along with the rest of the crowd will go to an empty table close to the cooking spit to enjoy the party. She will be a tad fearful of the player if they bested Crusher.
