idk how true this part is
He made a response video where he said he paid an animation company. And I'm inclined to believe this was the case. Presumably he would have wanted to make some revenue off this video, don't know why he would trust a child to animate it. Maybe a 15 year old did some work at the company that produced it, but idk why people are try to portray him as some sort of a creep.
The guy wanted to make a video for his channel. The video turned out to be cringe and he chose not to make it public. But in the small timeframe it was up, someone took it and spread it across the internet.
