On the planet called Kullgroon, there existed a native creature resembling a spider. These arachnids were a species characterized by blue skin and a remarkable ability to reform their bodies even after being destroyed. While journeying through a cave, Lando Calrissian found himself under attack by numerous small spiders. Despite successfully navigating past this initial threat, he then encountered a significantly larger spider. Calrissian eventually came back, accompanied by a group of Petrusians whom he had liberated from slavery. Armed with melee weapons, they battled the spiders as they advanced through the sewers.
