Dr. William Heyborne from Morningside College states, "The toad appears to be a great plains toad. As for the red bubble, I can't tell for sure. It is obviously attached to the toad and appears to be coming from a hole in the body wall of the animal. My guess is this is part of the toad's lung, which due to the pressure of inflating and being bitten by the snake has simply 'popped' out of a tooth puncture. "
