4 letters...B...B...T....Q
I saw 6 of the letters on the chan. B,S,A,B, T Q. Adds to 61, which could be dog, God or China. The first three entries. Year of the dog (Chinese). Every dog has his day. God is an elf on the shelf sort of. Just throwing it out there.
If you watch the video, one of the kids flips them and turns around the white stocking in the middle to show an "A"
