Not really looking to kill Looma just yet, but

Ganondorf's face looks really punchable. Like, he has only two arms, but he's just enough of an asshole that she might consider him an honorary Tetramand and call dibs. As wise/unwise as that may be she really doesn't think these things through

Plus Spike did say find the biggest, ugliest brute she could and punch them until they pay her to leave, so really, this is a two birds / one stone scenario.
