The Better Universe mod adds a mob called Pro, which has 1001 HP and 251 damage. When defeated, it drops a Pro Diamond. The mod also adds a Frost Stone, which you can craft with Stone and Blue Dye. The Frost Stone is a portal block to enter the Pro World. You can also craft a Pro World Portal Ingniter, which can only be crafted with Blue Dye. The mod also adds a Super Stone, which you can mine with a stone pickaxe. There's a secret crafting method where you can craft 2 stones from a Super Stone in the crafting table. The Super Stone is the main building block of the Pro World dimension and can often be found in the Pro Plains biome, which is in the Pro World dimension. In the Pro World, there's an uncommon item called a Basic Orb, and a mob called Pro can open and close doors. You also need a Stone Pickaxe to destroy the Frost Stone. The Better Universe mod adds other things.
