Gang boss Gat Arat (really, that's his name) has a new master plan!
And so the reign of terror begins!
Well, long (and kind of boring) story short, Gat Arat threatens to nleash even more exploding pigeons on the city unless he's paid off, Blue Beetle thwarts him, the end.
So, yeah, pigeons are a menace to whatever city you live in...
