Unlike Season 7, which has only 20 episodes due to six of its production slots being occupied by No Time to Spy, this season was split in half; Season 9 consists of what was originally the second half of this season. Thus, this season has the fewest individual episodes of the series thus far, although The Really Loud House's seasons both have fewer segments within more production slots due to the series' regular use of single-segmented episodes.
A former image on Paramount Global's content distribution website mentioned that this season would have brought the series' episode count to 196, giving it 20 episodes like Season 7.[3] However, since TV guides list the season as containing 13 episodes, it is likely that it was originally renewed for 20 episodes before having its count increased to 26, then split into two separate seasons.
To have Bobby as only member of the Casagrande family to appear (albeit only via video chat without a speaking role), after Season 5, and the first one to do so after The Casagrandes ended.
This wouldn't have been the case however, had Season 8 not been split into two seasons, as Season 9's "Meet the Purrents" features Carl.
This is the only season (to date) in which Bobby does not have a speaking role.
To not have any episodes themed around pranking, after Season 6, as well as the first season to not have episodes with a similar premise to the AprilFools'Dayepisodes.
To have a story arc with each episode using a common title, after Season 4 and Season 7. This is also the second season where the common titles of each episode in the arc are a prefix, after Season 7.
To have Lincoln voiced by only one actor, after Seasons 2 and 5.
This is the last season:
To use the Skater Dudes font in the title cards (excluding the French and Italian dubs, which continue to use it afterwards), as the show's crew faced legal issues from the font's owners during the production of "Europe Road Trip: A Knight to Remember".
To have its episodes' production codes and packaging codes align, as the second half of this season got split off into Season 9, and the ninth season in production order followed suit due to a network-wide trend of Nickelodeon splitting their shows' seasons into two seasons for packaging purposes "to keep their sizes more consistent with the season lengths currently consumed on streaming services where all shows ultimately get added".[4]
To air on YTV in Canada, as a result of Corus Entertainment not renewing its rights to broadcast Nickelodeon programming on its channels due to financial issues. The series going forward will premiere new episodes on the Canadian version of Paramount+.[5]
All episodes had a 2024 copyright notice (including the EuropeRoadTripstoryarc episodes which first premiered in the EU that year and then they premiered in other countries before they were aired next year in 2025 in the U.S.).
This season and Season 9 have the least amount of full length episodes both containing only one.
Unlike Season 9 however, this season also has a double length episode giving this season two episodes past the regular length.
Luan and Lisa have slightly deeper voices in this season due to their respective voiceactresses aging.
