I fill my wellies with gunge and slide my feet into them before adding some to my hood and putting it up, I also pour gunge in my suit and then go outside for a walk. The gunge squishes in between my toes as I'm out and I feel it run down my belly. I get back and start to trash my rain suit more and more, covering myself and adding more to my hood. I finish with custard and remove my boots to see how much is inside.
