I described it to someone as a rhinoceros sneezing. It was loud and the snake was very small. Best part is the culprit was at the front of her tub, mouth wide open and waving her head around like the roar was coming out of her mouth. Heard it over the loud TV which was promptly muted, scared the dogs, I was desperately wishing for my gun as we all crept over to see who had broken into my house and was now having violent bowel movements in the snake room.
Yes, that was a funny night.
