I was able to do some caving/adventuring last night, and in so doing I found some crazy shit. First, two zombies dropped crops: a potato and a carrot. So I've got those rotated in at Harvest Moon Acres. In sealing up the extensive caves under my evil lair, I found a skeleton generator. The chests had enchanting books, so apparently there's a new enchanting system in this thing. They also contained cacao seeds (new crop!) and a saddle (?). I'm not sure what the shit the saddle's for...a horse? Beats me.
That was it for goodies. I was able to cave way the hell down but really didn't find much of value. Some lapis lazuli and redstone. Don't know what to do with those, but I'll eventually wiki all of this. Not a great haul for caving, I was hoping to run into some diamond and an abandoned mine. I met my end with the spider jockey inside a massive abandoned mine, it was like Moria down there. I want to see another.
Anyhow, I had spotted the cacao pods on trees in running through a jungle. I hate the jungles, so didn't bother getting the pods. Now that I had the seeds, I had a clue to how it worked, so my last adventure was to get me some jungle saplings. Got a bunch and headed home.
Last bit of work was to experiment with the jungle saplings and bone meal, corral a cow that had wandered near my compound, and do some terraforming to benefit a bigger farm. Also some decorating and lighting -- crafted jack o' lanterns as a joke (I didn't think they'd be in), and the things are incredibly bright. I suspended a bunch over the farm to keep it well-lit and safe.
Sharing pics of the farm...
Shot of compound and surroundings. The jungle sapling experiment paid off, look at the size of that

er! I climbed to the very top but didn't make an exact count of the height. Maybe 30-35 blocks hgh? I love the goddamn thing. It pops!
Shot from inside the compound facing in the other direction. Glass ceiling, and if you enlarge the pic, you can see the corralled cow over there on the right, just above the cobblestone house line.
Close-up of house and jungle tree majesty. Bright green is potatoes and young carrots.
Next up is to collect more jungle saplings to even out the roof, it looks weird with just one on top. Also, I'm wondering if I can use jungle wood to "extend" the trunk of that jungle tree down into my house, in the hope that I can attach pods to it inside the house. I'm hoping the vining will propagate down the trunk, I like that look for the interior.
Then I'm going to have to pack it up for a long haul, caving near my joint is getting me nowhere. I'll likely write down my home coords, get in a boat, and sail, and I'm not returning until I've got more crops and diamonds.
