A spider-like creature was native to the planet Kullgroon. The creatures were arachnids with blue skin, that had the ability to reassemble itself after being blasted. Lando Calrissian was traveling through a cave when he was attacked by hordes of the little spiders. Although Calrissian was able to get past the spiders, he was met by a far larger one. Later on, Calrissian returned, but this time with a group of Petrusians who, he freed from slavery. With melee weapons, they fought the spiders as they made their way through the sewers.
