Kangaroo inflatable

Hello, I have some troubles going on in my model. I am trying to get a pressure on meshes… Some days ago this script worked for some parts of the meshes, then I tried to solve it to work for all of them but it just got messy…

If someone have time to have a look, would be awesome!
