It is your choice to soak your snake. Mine have taken baths for years. Not often but yes I do. In the summer when I have them outside in the privacy of my back yard they will climb into their wading pool sometimes for a swim all themselves. They like it even though they are in the shade. Blowing bubbles? Don't sweat it. I've seen snake bubbles a lot during my snakes swimming adventures. BP's aren't China Dolls even though the internet would like to claim otherwise. Doubt if your snake sucked any water in. If it did, which I highly doubt it, it will be fine. Have my snakes ever encountered an RI? No they haven't. Scale rot? No scale rot either. Relax and enjoy your pet. Take care.
