Those giant gobs are not the Blob reappearing, but instead the result of developer not completely reaching a section of the film in its canister. I actually still don't know exactly why this happened, but I think this part of the film was pinned under part of the plastic spool, and just stayed covered during each stage of development, most importantly during the actual developer's coating. This is not the worst of darkroom failures by any means, but it's still a little setback. Thankfully these were taken down the street, so I can go back and try again.   :-)
