A dwarf rotsucker.

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.
