Well, it finally happened. While looking into mapping Amiga games for Captain Planet, my good friend HandsomeStrife found a website that has ALL of the Mr Blobby levels (the amiga versions, but they are laid out identically in the DOS) mapped.

Now the maps do not contain items (like apple, ice-cream and so on), but it's a great starting place that saves us a lot of time. You can plan routing for every level with these maps, for instance.
My next plan is to try and add to these maps the various items on them, so we can start exploring level skips in Blobby%. I'm also going to try out a different version of DOSBox that allows for savestates - an incredibly useful way to experiment with item-combos.
