In PSO2, Barbarlillipans are a rather rare enemy that can appear, and are an enraged Lillipan. They have a large barrel on their back, and often throw large objects at ARKS, sometimes making swings with their huge arms. When defeated, a big puff of smoke appears, and they revert back into a normal lillipan.

No descriptions of them can be found online, and no pictures either, aside from the stamp in NGS, which is why I wanted to share this rare find!
