I have an idea! The quicksand biome! Surface blocks are quicksand, and quicksand acts like it does in the quicksand mod! Also, rubber boots, black with orange soles, as a new armor piece, and if you wear them in the quicksand, you'll sink slower! I've watched plenty of videos of rubber boots in deep clay mud on Youtube! So, that explains why I am posting this! Also, certain blocks are glitching, like chests not opening, and lava not causing fire to show up! What's going on?
