"Through your eyes, brothers, I finally see the world for what it really is. This city is infested. Eight million parasites, scrambling around in their pointless lives, spreading disease, forcing us to live in the shadows, like vermin. No more! They are the true plague. Together, we shall rid this city of humanity, and reclaim it for ourselves".
"You build your cities on foundations we gnaw through."
"Humans build their castles of stone and steel, while I dwell in the living, breathing maze beneath."
"Ninlarra... a curious tidbit these humans ingest. It slows the burrowing of their own bones, a struggle well known. Perhaps it’s a lesson: even the mightiest structures crumble from within."
"I do not wish to fight. But cast a stone into the lake, and the ripples will return to you." - Master Splinter
"A rat in a maze is free to go anywhere, as long as it stays inside the maze."
"It annoys me a bit how people like squirrels but not rats. at the end of the day they're the same thing, except that squirrels have had a better upbringing."

Rats also have a fairly large fat pad present within the scrotum; which can make the testes look even bigger than they actually are.
"Seek the hidden passage, not for escape, but for new beginnings. For the Wheel of the Burrow always turns, offering fresh paths for the daring."
"The Rustle of the Ancestors echoes in the walls and tunnels. Hear their wisdom in the shifting dust, and remember the paths they carved before you."
