I would not love this situation at all, but I think, I would reluctantly call and hope, he slows down on the turn. I think this pot sized donk bet is a draw or a weak made hand looking for "protection" more often than a nutted hand like a straight. The issue is, two pair or even sets might also take this line, because the board is so wet. So if you folded, I would not consider that a mistake either. The tournament just started, and with 10 minute blind intervals you have lots of time to find cleaner spots than this.
