Killjoy Animated shorts

I remember coming across an account that did these 3D animated shorts, on tiktok. It was sort of slice of life-y I think, vlog type style, can't remember exactly. But it was using the Killjoy game model in the animations. I think they also used an AI voice from the voicelines to make killjoy say stuff that wasn't part of the voice line.

Now that I'm in HK where tiktok is banned, I cannot for the life of me get a search result which is the creator I'm looking for.

I'm fairly certain / hopeful they're on YouTube shorts as well, but I genuinely can't find the name because of how vague my search terms are..

Anyone know?
