In a shocking turn of events, Penwiper got his nose scratched. Again. Here it is after it has healed a couple of days.
Penwiper and his scratched nose
Penwiper arrived on my desk just as I captioned the photo. As I put him in the tower behind my desk (the same one as pictured), I also felt a small scab on the tip of his left ear. I really wish he didn't annoy his armed housemates so.
