Actually, I think the aliens would want there insulation stuff back!
I wonder if it can be purchased? I have been thinking of all sorts of stuff to do with it. If it could be glued like wall paper it could be put inside on the ceiling and walls and wall papered over it if it's smooth. Maybe on the roof it could be covered with cloth like the Holiday Ramblers were.
That would make it much more comfortable during colder/hotter weather.
Or I could just buy a new one! Well no, no I cant.
