This is room is probably my least favorite ever, but I've almost worked it out. The one thing I still need to deal with is the tar blob at 1.
I need a tar mother alive in order to clear out the blob and access all the alcoves with tar babies, but it's hard to get in and out of that area. There's only one route in, and all routes out can potentially be overgrown with uncuttable tar. This suggests that I should clear out one of the blobs marked 2, but if I do that then I get more babies than I can handle.
So what approach should I be taking here?
