Yeah... my friend showed me this last year. I was gonna watch the second one eventually so now that I saw you posted this, I guess I will!
And so after watching it, I assume that each video had a moral, despite the bizzare and macabre endings, and not to mention unexpected to any first time viewers:
Green is not a Creative Color: Overthinking is bad.
Time: Don't waste time? lolidk
Not sure if that's correct, I never researched it.
