It'd be interesting if someone created a topic showing things that does actually make sense as well! I.e. could *anything* in Sonic be scientifically plausable (ignoring the whole 'Sonic on Earth' side of it)?
I've got a large Sonic Generations poster on my wall, and in the background of the poster is that rocky 'mountain' with a waterfall coming down from it. When I see it, I keep thinking to myself "how would that actually work in reality?" This is the picture that got me to make this thread:
I could assume that it's some sort of geyser, but even then the rock formation wouldn't really explain it either. Whatever it is, it certainly can't be a lake up there anyway!
If anyone wants to be facetious, the subtitle explains it already.
