Dwarf rotsuckers were cousins of the larger Deepwoods rotsuckers. Many dwarf rotsuckers lived on the crossbeams of the Sanctaphrax Forest. As with the larger rotsuckers, dwarf rotsuckers spat up a liquid and bile over prey that soon solidified into a hard casing from which there was no escape. The fumes inside the casing soon killed the prey, and the bile digested them over the course of a week. The dwarf rotsucker then drilled a hole into the pod with its mouthparts and drank the contents.
