Just watch the episode!
This is a compilation of the cleanup shots you did of a 12 minute long Ollie and Scoops episode. Although your work on the show is great, given that it has a huge team of animators and artists and so and so, I really don't recommend posting incomplete packages or demo stuff like this to Newgrounds.
Also I don't know why you aren't coauthored on the episode itself.
EDIT: Newgrounds is more for completed/finished submissions that can stand out on their own.
I've seen some people submit clips from collabs they've worked on, which is fine, but they're all broken up into different segments where one person completes each part from start to finish, backgrounds, characters, and all. They may use external audio, but I won't touch on this, but each part could stand out on its own.
For example, the Half Life Collab from early 2021. Each bit could stand out on its own as a separate submission. This is actually a better example, as each part have a decent run-time and have their own audio + writing. Other collabs may only last for 5-10 seconds and are derived from existing audio, usually the source material if it's a 'reanimated' collab

Here, the process is completely different. Many different people work on many different bits at a time, with 11 other cleanup artists, which is pretty much drawing over someone else's rough animation to use in the final product, so I'd hardly call this a finished work.
It's not disallowed, although I would rather you submit your own stuff.
