We all know Donkey Kong and Diddy Kong wear clothes. Same for the Kremlings. And Banjo-Kazooie and Conker are even more blatantly clothing-wearing than DK and pals, so there you go. They also use a lot of items made of wood, steel, even rock, possibly taking after the citizens from the Mushroom Kingdom that attempted colonizing their isles all those years ago.
Now you might wonder; why the hell is this a blog post? Well, here you go; where do they get their resources?
I mentioned power sources not too long ago, but I mean, stuff like DK's television and K. Rool's PC didn't just fall out of thin air, now did they?
But the resources they have... where do they go?
I am presuming the Isle o' Hags, as large as it is, has some specialists whom buy the resources in bulk and in turn make objects of it.
Resource 1; Wood
Wood is abundant and necessarily for life nearly everywhere. Chop down a tree and you can make stuff with it. DK Isle abounds in wood, obviously, but it's mostly tropical. No, the real deal is the Northern Kremisphere.
A mainly forested region, abundant in large, stately, ominous redwood trees. (sequoias?) Most notable in the Kremwood Forest. The little isle in its centre provides a place for the Mekanos factories. They, presumably Kremlings, chop down the trees for use as fuel, building material, and suchlike, if the level Ripsaw Rage is of any significance.
So, they ship the wood to the Isle o' Hags where it gets changed into useful appliances. The Kremlings have a cutting-edge scale of technology for some reason with large airships... which brings us to our next subject;
