Don't worry, it's not blood. (My first thought - I'm always the alarmist). Turns out they did an art project today with chocolate syrup. S was covered. It was in her hair, between her fingers, and up her nose (ewwww). It was a take a bath the minute we got home night tonight.
Oh, and never fear - the chocolate came out with a ton of pre-treating and soaking. Whew!
