Kazooie is a wisecracking, obnoxious, sassy, cheeky, hot-tempered, slightly egotistic, tell-it-like-it-is loudmouth and "teen" bird. This could be because almost everyone that she has met had insulted her in some way. Bottles, for example, called her a 'strange friend' and asked Banjo if she could talk and Mumbo Jumbo called her the 'filthy feathered one'. This could also be why Banjo and Kazooie are such great friends since Banjo hardly ever insults anyone (and if he does he usually apologizes). In some cases, she also can express sarcasm. Despite Kazooie's foulmouthed rudeness, she never insults Banjo at all. Being best friends and both with different personalities, it's obvious that she respects him greatly and will stop insulting upon Banjo's words, proving her loyalty to him, however she insults everyone and always make trouble. Despite all her flaws, Kazooie still has a good heart, always willing to help those in need (Provided that it has something to do with the adventure) and she has a strong sense of justice.
