Sorcerer with Bloodline Familiar Archetype has the option to choose a familiar, but many familiars seem to be missing. Specifically, the Greensting Scorpion is not an option. It's an option for a follower, but not a familiar. Sources loaded include Pathfinder RPG Core Supplements, Familiar Folio, Bestiary 5, and Bestiary 6. I'm also using the 6.08.00 version.
