Challenge 23
Atom is very small. Which means that the crab he's fighting is also small.
Across the street, we can see small pictures of people fleeing. We remember that comic books' exaggerated perspective makes distant people look very small.
In fact, those people are actually too distant to see a small crab on the other side of the street. Besides, they're not fleeing the crab; they're actually coming closer to it by a small amount.
Which means that those people are probably fleeing something much less small. Atom's heroic victory over the crab will be small consolation.
