It was weird but in a highly-useful way. A desert temple I found was generated in such a way that the wall of the trap shaft was removed/not-generated because a cave ended at that exact point. No other part of the temple was damaged, and because of RNG shenanigans there also happened to be a natural and perfectly placed cobblestone generator right where the chest would be.
I quite like to see unusual terrain generation. I've seen a few really interesting ones, but probably my fave is what i dubbed Snake Head Pass, and is entirely natural, generated around 1.5 when i first started this world, and very close to my first main base. I've never built on it, left it as one of the natural wonders of my world
Way to go, Minecraft! Seriously, though, that looks a lot less like a snake and more like a (baby?) dragon..the head is the large probably-flat outcropping on the left, the wings are in the center, and the tail is on the right.
This thread is just so perfect for funny captions...
Regarding the Spruce on a Ledge pic, the caption would be "okay, if I time this just right, there should be enough water below."
Regarding the natural arch pic, you should totally make that arch into a statue of some sort of large dog breed (maybe whatever breed inspired the myth of Cerberus the 3-headed dog guarding the gates of Hades?). The crown of the arch would be the head, the forelegs would form the sides of the arch, and the shoulders and chest would form the top of the arch. You could then use the caption "Abandon all hope, ye who enter--SQUIRREL!"
The Meaning of Life, the Universe, and Everything.
This isn't necessarily weird, but it's one of my favorite natural generations. A very wide waterfall with a hollowed out area behind it in the mountain. Once you step inside the waterfall there is a large room with a skylight that was naturally generated. So essentially there is a large curtain of water. The first picture shows a house I built on this location because I loved it so much. As you can see, there is torch light coming from behind the waterfall where the room is.
If anyone wants to see this for themselves you can check it out.
