Haha, I agree with moar people actually getting squished even if done in a comical fashion. Hinting at tinies perishing underfoot and actually seeing tinies perishing underfoot there is a huge difference in action feel. XD Not to mention that is a beautiful chance for a tinies perspective shot of a giantess ripping through his city before lights out.
