Well, that took a while, didn't it? Anyway, today I'm going to tell you about another invaluable resource of mine: the Super Mario Wiki!
This Wiki has been my go-to place for all the information about items, characters, worlds... you name it, it has everything about everything! Whenever you suggest a icon I haven't heard about before, this is the place I visit first. Even when I do know, I gotta pay it a visit to get some beautiful, high-resolution reference artwork.
So, if you're looking for some new icon suggestions (keep 'em coming!), want to read about the Mario universe, or just want to stare at pretty pictures, this is the place to go:
