Bummer...well there are worse places to be trapped. At least he had water. I wonder about the feet thing though. Keeping your extremities warm is a priority (the feet)...but getting out is another big priority. Gaining attention could do it.

I wonder if you could clog the drains...turn on all the water and see if the flooding gets noticed. Although it would make your situation worse if nobody did notice.

Puzzle, puzzle. I'll have to ruminate on this awhile ;^).
