Having a soft shell was hard, especially when it came to being in high school. The constant brushing past people in the corridor, the constant 'arm the shoulder bro' thing his friends do, the occasional touches to his shell in general were awful, even if he was beginning to get used to it.

Donnie had never told anyone he had a soft shell, that was his secret. The only other person that knows is Splinter. Of course he has tried to protect his shell with inventions but he just never had enough in the sewers to make anything. He's always thought that some 'Battle Shell' would be cool.

So here he was, dealing with it once more in the corridor of the high school. Normally it wasn't so bad, but considering he hadn't slept and was already overstimulated; the little brushes on his already sensitive shell was doing it for him.
