Seed: mister

This is a definite one you should check out. Plenty of coal, and two patches of sugar cane. Then there are two waterfalls next to each other, and so many cool caves and cliffs, and a floating island. Plenty of water also. Very cool seed.

Seed: blocky

Not much to report on this one. One chunk of coal and one sugar cane plant. There is quite a bit of snow, and nothing that stands out.

Seed: widow

This one is pretty cool. There is some exposed coal here, but you may have to work a little to get it. There is sugar cane growing in two different locations. Lots of cool land formations , and even a little waterfall.

Seed: superman

This one is really good if you want lots of flowers and mushrooms. Also plenty of sugar cane and coal. This seed features a very short waterfall. You could really classify it as a spring. No lava.

Seed: chunks

This one is pretty decent. Has a lot of sugar cane, one chunk of visible coal, a desert with some cactus plants, and plenty of water. No cool features like waterfalls or lava though.
