A spoiled house rat gets flushed into the chaos of Ratropolis, the sewer city built from junk and dreams. You’re a local rodent used to the dirt and danger — and Roddy, in his tuxedo and ego, sticks out like a diamond in the drain.

At first, he’s arrogant and useless, but your choices decide if he stays that way or learns courage, loyalty, and heart. Work together, mock him, or even fall for him — just remember, every lesson in the sewers comes with mud.
