Extrapolated Decor is the building-materials section of Minestrappolation. The mod adds a plethora of new building blocks for you to classy-ify your builds with, ranging from Sandstone Brick to Coils of Rope. While most of the blocks in this segment are purely decorative, some are also equipped with other functionality, such as the Slime Block, which causes mobs to sink into it.
