"Another Giant Land tileset? Dude, how many of these can you make?!"
More then you think...
Anyways, another Giant Set, and not the last one either. You've seen giant Grasslands, but what about Giant underground tilesets? Yep, this is from SMB3 as well, the original game that had the idea in the first place!
Some credit goes to Tornado for the palettes and his graphics so I can replicate it and enlarge it.
