What do I do in a Minecraft SURVIVAL world?

I created a world in 1.7.2. I don't think there are any jungles in this world because I've searched for days and I haven't found any sign of a jungle, so I can't do a treehouse.

Any ideas to do in this SURVIVAL world.

Right now I just have like a 7x7 small wooden house next to a lake/bay that connects to the ocean.

Ps vita froze after locking screen in PSN store?

Okay, so I got a PS Vita on December 10th 2013 (Only a week ago. ) for Terraria.

I've been downloading apps to the memory card and playing Tearaway, which I bought at GameStop. I've been loving this system so far! It's absolutely gorgeous, powerful, sounds great, and has a future game library that's looking really great! (Minecraft Vita edition! Woot!)

However, today I had a very strange issue.

Terraria on the PS vita is supposed to come out today. So I went to the PSN Store and searched for Terraria to see if it came out yet. It didn't. I put the system in lock mode and messed around with my iPad for about an hour.

I decided to check if the store refreshed since, and unlocked my vita. I searched again and once more the system told me it couldn't find any matches for Terraria. Darn. I locked it again.

Okay, so here's the point. Another 30 minutes or so later I became incredibly anxious to play Terraria on my Vita and went to unlock the system again to check if it came out once more. To my surprise, my system wouldn't unlock! The screen was showing the lock screen image with the page you have to flip, but as many times as I tried it refused to unlock. It let me lock it again and unlock it with both the ps and the power buttons. Still wouldn't let me unlock. The system was responding to the buttons (power and ps button. ) but the touchscreen refused to work. I was scared it was a problem with my touchscreen.

Then it gets weird. I held down the power button, and the power off screen appeared. Again, I was unable to tap any of the onscreen buttons. But this menu let me use the joystick to select turn off. Then I pressed X to confirm my selection and the system shut down. When I turned it back on, the screen worked just fine! O.o It let me unlock the system and start various apps, as well as typing on the keyboard, swiping, multitouch, and holding. If it was a broken touchscreen, why did it suddenly work?

So I thought it was weird but I figured as long as it was working I had nothing to worry about. I started the PSN store again and searched for Terraria once again. Not yet. I locked the system. This time I wondered if it would work or not so I instantly unlocked it again to see if it froze. Sure enough, the system's touchscreen was frozen and I had to power it off with the buttons again.

I restarted it and attempted to reproduce my steps to see if I could get it to freeze again. It won't freeze! I searched for Terraria and locked the system several times, and it always unlocks and lets me use the touchscreen just perfectly!

So, my question in brief is, what the heck happened? Is my touch screen broken? I treated it with care and it's only a week old, so I doubt that I broke it. And after a reboot it worked fine! So unless something didn't make a connection every time I tried to unlock it, the touchscreen is fine!

Did the system freeze up? The icons (Wi-Fi, 3G, battery, time, etc. ) were animating and changing so this is also unlikely.

And lastly, was it caused by the PSN store? Or was it just a coincidence that it happened in the PSN store after searching for the same thing?

Thanks for reading! I really hope it was just a weird software glitch and not some mega hardware error! But if it was I'd like to know because my system is still under warranty as I got it just a week ago.

Are there any jungle biomes in Minecraft 1.7.2/1.7.4?

All of the worlds that I've created since the 1.7 release don't have jungle biomes (or at least non that I can find).

I spend hours searching for a jungle biome in a world and I can't find any. I search at the desert borders because it there were usually there before 1.7, but in the desert borders I only find Acasia Wood trees.

If there still are jungle biomes, where are they located. Which biome are they next to? Desert, Mountain, Ocean, Plains, Forests?

Minecraft: Can't screenshot my coordinates?

So ever since minecraft 1.7 came out, I have not been able to screenshot my coordiantes or my inventory… I use to be able to but now I can't, and I know this is not a new feature cause other people can still do it… So is there a way to fix this so I can screenshot my cordinates and my inventory again? *Also I can take regular screenshots just not the ones of cordnates or inventory*

Minecraft: How to stop Internet lag?

So by internet lag I mean when I'm playing minecraft hunger games, when I click on a chest nothing happens. I wait usually about 5-10 seconds before something actually appears on my screen but by then the chests are empty and I have nothing. So why doesn't anything come up when I click on these chests and how can I fix it?
