Bob and the Blob Publisher's Summary
Bob's day is off to a bad start. He is abducted by alien blobs and is put into a zoo, while the rest of humanity is being taken to be slaughtered and turned into burgers.
He has had better Thursdays.
Bob's handler Fred befriends Bob, and the two of them try to change the legal status of humans from food to intelligent life so that the slaughter ship can be stopped and everyone returned to Earth. It is not easy as there are a lot of not-very-intelligent life forms on that ship.
