Rick and Julian come up with a one shot deal with the prison guards to raise money for the trailer park. Bubbles decides to throw a concert and Julian books Helix to play. They setup Trailerstock and realize Queens of the Stone Age are playing the same night.
Ricky and Julian force Josh Homme to bring their crowd to Trailerstock. The cops come and try to arrest Ricky and Julian before they're backed up with their story of saving the park. Queens of the Stone Age play their set and they make enough money to save Sunnyvale. Clont tries upping the ante on his deal before Josh pays him off and Barb kicks him out. Helix upset with not getting paid, put on a concert for Ricky and Moe.
The season finale for The Animated Series rocked, literally. Trailerstock was a success and Ricky got to see his favorite band with his grandson. I can't wait to see where the show goes from here. With the amount of content TPB has with animation, we could see many more animated seasons coming soon.
