Rainbow Dimension

It would be cool if there was a new dimension added to this game similar to the plains biome but with a giant mountain waterfall and lake. You would be able to trade friendermen (short big-headed endermen of various colours) diamonds for items. They would be found in the cherry blossom village in the center of the new rainbow dimension. You would need to craft a lot of light blue wool and then light it on fire to create a rainbowy portal to this new dimension. You would easily find sheep and bunnies in this new dimension.
