King Aracobb is the king of all spiderants. He is located in the Trash Coast, directly west of the transition point and will appear during the "Bait And Switch" mission after the abdomen of Queen Tarantella is placed as "Bait". He is not large compared to Queen Tarantella but is the same size if not marginally bigger than a regular King Spiderant. King Aracobb will respawn after completing the related mission, making it possible to harvest experience and items.
