These people can be found in YouTube 찍고 animation test https://youtu.be/u_2zdCoCcxE artemovan86 reel https://www.youtube.com/watch?v=l5591SmmjZA
This isn't the toon boom file but a video of an animator from Korea who did this animation, his account is @찍고 or referred as jjigho, but this is an incredible find! He did a animation test from an episode called "The Pool" from late 2012 or early 2013 and he is showcasing this in 2021 (8 years later) as he tries to replicate the animation style (like Overseas Korea). Sadly he couldn't participate but here you go, someone should archive this. There's also another animator I found, but just the clips he animated. He is @artemovan86
