People keep bringing up Mickeyjunk Mountain as proof of Oswald's mental instability, but remember that later events in the game indicate that he might not have had much choice about his location. He needed to guard the Blot's bottle, and even if he got to pick out the location of that, the remoteness made it a good strategic location to put something that's constantly spewing out monsters.
It's also not clear whether he deliberately put all of the Mickey paraphernalia (even if he did, it could have been along the lines of "let's dump it all over there") or whether it congregated there naturally.

imagery shown in some of the early concept art is really going to come into a future sequel. It seems like the developers (or the executives, if you want to be cynical) discarded the stuff that really pushed the envelope in favor of a tone that was more similar to a standard Disney movie.
No idea who Julius is. Guess that's the point, eh?
