Due to BOb's limited vocabulary - much of which requests chickens - not much is currently known about BOb except that he, or rather they, have an affinity for Hens and Roostros. It is unknown what happens to the chickens BOb requests.
BOb appears to be multiple Pink Slimes stacked together covered in a trench coat and a fedora, badly disguised as a Rancher.
- Since BOb is capable of communicating with Beatrix via StarMail and utilizing the Range Exchange to request chickens, this may signify that slimes, or at least the slimes that compose of BOb, are sentient.
- Though it seems they have a very one-track mind since their entire dialogue consists of requesting chickens, if not gobbledygook.
