I can confirm both the pending things. Ghast tennis, you can just hit the fireball back with anything including your fists. And yeah you can use the fishing rod to grapple mobs and pull them towards you.
So I was poking around in Survival Multi player with my bud, even though hell stuff doesn't work...
There are Watches, it tells you the time of day with a little dial, built with 4 gold ingots and 1 redstone dust thing.
It has a dial that tells you how late into day or night it is.
Gold dust comes from the golden blocks in the Nether, it can be reconstructed into these blocks by filling the 3x3 grid with the dust, but when you place the block and break it you only retrieve one speck of dust back, so be wary in placing it.
Pig Men Zombies in the hell world will attack the Ghast if you lure a ghast fireball into a pigman though O:
There are 2 varieties of Fish that you can catch with a rod, fishing works by just right clicking with a rod equipped and waiting until the bobber goes down, then you hit right click to pull a fish out. I haven't checked what fish do in Single Player yet. (You can't smelt them, I tried that in SMP, not sure if it will work in Single Player)
You can use a fishing pole to get fish out of any body of water as long as the bobber is bobbing, so there should be adequate space in the pond for the bobber to go down a little.)
I tried fishing in different environments in naturally occuring waters, the fish types are the same...
Any jack-o-lanterns you find you can actually turn into lit jack-o-lanterns and they emit light like a torch (Not as much I dont think..not sure.) They act like torches and melt snow, however.
Halloween and Christmas go hand in hand, too.
The formula for that is a jack-o-lantern with a torch under it.
Ouch, a creeper just exploded at me from behind a door, and I wasn't even next to the door! Damn, that definitely does not seem good, can anyone else confirm that they can see through doors and still explode?
