The blimp thing could have been ...'parked' there for so long it's been overgrown with... orange mushrooms! And one of the gnomes collecting mushroom stuff got a bit too risky and fell, spilling his orange mushroom spores out on his way down. MUAHAHAH.
Basically, my view is that the blimp thing could be worked upon (adding more damage, detail and absailing gnomes...) to fit the rest of the piece, rather than being completely wiped from existance. I mean, my little story above has lamely given an explanation to it all. Sort of.
Can i attack 87? ^_^
