I flexed, and the shirt is no more. I can't keep skipping leg day.
I was inspired by:
https://www.planetminecraft.com/skin/buff-kirby/
https://www.planetminecraft.com/skin/buff-perry-the-platypus/
https://www.planetminecraft.com/skin/buff-doug/
https://www.planetminecraft.com/skin/buff-boy/
I didn't copy any of the skins, but I did use some of their pixel placement. I had an idea of what I wanted, and those skins helped me find what I was looking for.

You only just missed me still wearing the shirt. Luckily, PMC freezes stuff like this in time: www.planetminecraft.com/skin/buff-joeenderman/
