This project is just some undertale soul physics that I made for anyone to use, this contains the red soul, the blue soul, the orange soul, and the green soul. (the orange soul is not actually in undertale, but I included it any way...) Use if you want, You can give me credits, but you don't have to if you don't want to. Thanks to Toby Fox and Temmie Chang for creating undertale.
