Pooplosion, as dubbed by Keefe, is the unofficial name of a salve Physic had taken from the Hekses' house. It was described to be kept in a palm-sized jar, and it was said to be the color white. It was used in Neverseen on Fitz after his arthropleura injury. It cleared away the black veins on his chest, and from there it only took an hour and fifteen medicines before Fitz was cured. Its consistency is described to be goopy.
