Kill them!
(There's a limit to how many mobs are active at one time, and wool doesn't re-grow once removed, so get a pack of wolves and a bow and arrows and go hunting.)
Collect a load of stuff and then when you get home build something. REAL LIFE MINECRAFT!
Also you can dye the sheep and then take the wool which is a more efficient use of dye.
Too late, I'm home now. I did collect... uh, 4 buckets of water, plus sugar, plus red flowers, but can't build much out of moulded plastic and 12 litres of Coke. :(
it doesn'r rain on sand that is underwater - mad
also, I have a ton of that blue stuff if you want it
oh, and lava can fuck right off
(fell in with 3x stacks of mossy cobble)
You've got enough anyway.
actually, I don't, and I was specifically looking for more
so very hard to find - usually spot dungeons via glitches
Ah yeah, glitches and slow loading are great for spotting underground networks.
