A man shows me a group of purple parsnips in the ground and explains to me that they will have a purple turnip as a mother. As we dig down, the soil turns to thick black liquid and I find myself under the surface closely inspecting these parsnip/turnips. They are choked with ivy and water weeds. I pull one and deliver it up to the surface. It is now a small dog's tail and wags with pleasure at having been set free.
