Ep 2. I Wanna Punch Stuff

Trixie, Derek, Burger, and Ash go to a martial arts class to get in shape for an upcoming gig at a karate school. When Derek accidentally breaks a board with his face, Trixie decides to take over as the band's "tough guy" and learn karate. However, she quickly discovers that she is not as tough as she thought she was and struggles to keep up with the other students in the class.

Meanwhile, Iron Weasel's manager, Simon, comes to the realization that the band is not making enough money to support themselves and suggests that they write a commercial jingle to make some extra cash. The band resists the idea at first, but soon realizes that they need the money and agrees to write the jingle.

Trixie continues to struggle with her karate lessons and fears that she will embarrass herself at the upcoming gig. She confides in Derek, who suggests that she channel her anger into her karate moves. Trixie takes his advice and is able to successfully perform at the karate school gig.

Iron Weasel works on their commercial jingle and realizes that they are not quite sure what the product they are advertising is. They go to the company's headquarters to get more information, but end up causing chaos and getting chased out of the building.

In the end, Trixie learns an important lesson about staying true to herself and not trying to be something she is not. Iron Weasel manages to write a jingle, but it is not exactly what the company was looking for. They are left wondering if they will ever make enough money to support themselves as a band.
