In contrast to Banjo's personality, 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.
