Well, my first post and I had the same scare today with my new common Boa "Baby" Its a 24 inch male that I just fed for the first time yesterday. He has been in his new enclosure for a week. He immediatly went into his hide last night and this mornng I went in to check on him and he was not in his Scotch box. In fact I did not see him anywhere. I suddenly had a flash back to college where my Kingsnake got out. Anyway, he did as yours did and burried himself in the substrate.

I love the pic of yours peeking out. Very cool.
