Brentilda will help in the lair when you think she's just a bit strange by telling you : what pants grunty has , what she eats , went to school , favourite sport , favourite magazine..... but it helps ( i'm not sure if she knew about the quiz mabye she just likes to tell people that grunty had a band called ______ or she has new pants )
