Season 9 aired in 2012. Every episode in this season is rated TV-MA, except for "Big Bro", "Chicken and Beans", and "Zucotti Manicotti", which were all rated TV-14.
Season 9 was confirmed by Dave Willis via Twitter, by saying that 2 scripts were written for a second Aqua Unit Patrol Squad 1 season. It was said to have twelve episodes that will be made in this season to even out seasons, but it turned out to only have ten episodes. The theme song is performed by Mariachi El Bronx, alongside with Schooly D. This is the only season to date that has an extended opening for its theme song, only seen in three of the ten episodes ("Robot Horse Jet Chicken," "Fightan Tightan," and "Buddy Nugget.")

- When Matt Maiellaro first announced the title of this season, he made some rather bold claims. He stated that there would be twelve episodes of Aqua Something You Know Whatever, instead of ten. He also claimed that all the characters would be killed off and that "By episode 3 of the 12, there's going to be no more Aqua Teens..." Matt eluded to these deceased characters coming back by the end of the season. This idea of continuity never came true. Matt and Dave have been known to lie about future episodes to mess with fans, and many people had caught on to their shenanigans at this point. 
- There was rumored to be a dropped episode entitled "Circuit Attack." It is unknown where these rumors started and what the plot of the episode was intended to be. It is also unknown if there really was a dropped episode with this title.
- This is the only season that an episode airs in every week.
