Enderman & Blocks

I think you should add hundreds of decorative blocks. Enderman could sometimes spawn with one of these blocks and this would be the only way to obtain these blocks. If enderman can teleport between dimensions, it would make sense that they can pick-up blocks and bring them to the Overworld, even if the dimension doesn't technically exist in the game. I think this would be a very cool feature. These would be blocks from unreachable dimensions.
