So I havent seen anything about this around here, and I know alot of people love super mario so I bring you the super mario mod for minecraft(not my creation, just thought it would be cool to share it).
Click Me!!
It includes all the blocks and mobs and lots of cool stuff.
I have thought of making a super mario map but I dont have that kind of time to spare at the moment unfortunately, though I will get around to it when I can.
Have fun
