I was thinking that it would be epic to have a Tundra Portal. (I suck at coding, so hopefully someone can make this for me) Basically, you would make a portal out of snow or ice. (Same size as Nether Portal) You would add a bucket of water to it and like the Nether Portal, it will hum and glow a bluish color. When you go through it, you will end up in a frozen land. The first three layers will be snow, and 15 layers down will be permafrost. (Ice but with a durability of dirt) After those 18 layers, it will be the same generation as a regular world. (Stone, ores, bedrock) Unlike the Tundra, this generation will have trees, but the trees would be made of ice and snow. (Snow for the logs and Ice for the leaves) The land will be mountanous with flatlands of snow. When you find an ocean, the water will be 3 layers of ice, then water. Animals would consist of hares, polar bears, wolves, arctic foxes, snow owls, and moose. Hostile mobs would be the same as the other hostile mobs, but with an icey tint. I realize that this is a lot to ask for. But, if someone could pull this off, I think it would turn out to be a nice mod. Also, feel free to add on to this mod if you want to.
Thanks to Dingousa for some of the ideas
Thanks -Ares945
That would help, thanks :D. Now I just need the generation. Thanks a lot
