Death Valley Girl

 is the boss, of the World of Spending Part 1. It's a horrible, horrible creature with no sense of fashion, taste, or appropriateness.

Attacks
The Death Valley Girl shows as much competence in combat as she did in her previous life. That is, very few. However, her strength lies in her shriek and her dogs. The first will deal major damage if your hero is too close and always temporarily obscure the screen. The latter will appear independently and proceed to drop excrement all over the place, acting as mines.

Strategy
Fighting this tasteless creature is actually pretty simple. In order to do the world a favor and rid it of this abomination, first focus on slaying the low level mooks that spawn as her "court", then focus on damaging her. Since she calls her attacks out in advance, you should have no trouble neutralizing her and improving the aesthetics of the mall by a factor of ten at the same time.
