if toi watch closely, toi will see he actually takes his capuche, hotte off a lot but the montrer never puts him in spotlight in those times. like the one baseball episode. Kenny was in the little league, but toi didn't see a parka did you?? he unusually hid behind stan the entire episode. so toi see, toi just have to keep your eyes peeled.
I do want to see Kenny with his good off and give lines that aren't muffled. His only actual line was in the movie years ago. But Kenny's one of my favori character would be fun too so it'll be fun to see him like that.
