Here's a small little Mario Pipe hideout I made on an old server. I converted a cave into a little hideout, decorated it to look more like an underground level from Super Mari Bros, and built a little wool pipe on top. It features some basic survival supplies: a wheat farm,bed, workstations, a mining area, a gravel pit, and a chest full of nice goodies including some Mario-themed items! This could make for a good starting home or compact hiding spot - or a rest stop in a Mario-themed adventure map! The download contains a schematic for both the full build, as well as separated pipe and dungeon sections.
You may use this for anything, just please give credit!
