Sewer Urchin is needed to protect the sewers from his acrh enemy Sewer Czar and his army of filth. The Tick and Arthur decide to help Sewer Urchin defend the sewers from this menace and find out that there out of their league and that Sewer Urchin is their only chance for survial and gives him the respect that he always desevered. Sewer Urchin is one of my favorite super heros and this episode is his moment to shine. I also love the Filth monsters and there chant "Were Filth, Were Filth, we come form Filth were going to Filth." We also get to see Sewer Urchins home for the first time and surprisinly has a lot money and could be considered rich! This has one of my favorite quotes from the series.
The Tick: Man, you are so cool down here
Sewer Urchin: Oh yeah, down here I'm the aposhioes of cool
Arthur: Did you just say aposhioes
