Sewer Urchin is wicked cool in the sewers! The basic premise of this episode is that something (Filth) is threatening the sewers of the city and Sewer Urchin is called into action. Of course, The Tick and Arthur decide to try to help out and tag along into the sewers...and they find out that beneath the surface there is on greater warrior for justice than the mighty Sewer Urchin!

The heroes visit Urchin's apartment where he girds them for battle (with lemons, a crabclaw cracker, soap, butter, and little helmets) and where Tick and Arthur come to realize that Urchin is very rich and cultured. From there, the group navigates some of the many hazards of the sewer (Sewer Lobsters, Wallet Anglers) and Tick and Arthur realize they are way out of their element.

Eventually, the final confrontation between The Sewer Czar and the filth decide to side with Urchin, thus saving the city.

You are so cool down here!

Yeah, definitely check mate!

The character who gets ripped on a bit in this episode is Die Fledermaus; the episode opens with him losing in chess to Arthur and then whining about it, then he faints when Filth comes out of his sink, and finally he's humbled by Tick when he makes fun of Sewer Urchin back at the diner later.

I think there are several reasons I love this episode. First, it's great to see Sewer Urchin finally get his due; in this episode he is the very apotheosis of cool. Second, it's funny to see Tick try to adapt to the sewer environment; and finally, it's funny to see Die Fledermaus humbled a bit.
