New mobs and biomes

We have the blaze and the breeze, but what if we had the blossom, blizzard, bolt, and the barnacle? (Try saying that five times fast!)  The barnacle would spawn in the ocean and if you kill it you get barnacle rods. The barnacle rods can be used in a potion to make a potion of (Potion name), which gives you slowness III, resistance II, and water breathing. The blossom would spawn in a new biome, called the flower forest. The blossom is a passive mob, and it drops blossom rods. They can be crafted into shrub charges, spawns a bush you can walk into and when you walk into it, it heals you. The blizzard spawns in tundras, and if you kill it you get (You guessed it) blizzard rods. Blizzard rods can be combined with snowballs to get a flurry, which when you throw it at a player, it spawns a lot of snow particles on their screen, and gives them the freezing effect. The bolt spawns in stormy valleys, a place swarming with lightning, and when you kill the bolt, it drops bolt rods. The bolt rod can be crafted into shock powder, in which combine with a bundled you get a bag of shock powder. When placed on the ground, it produces a power signal of 7 when stepped on, and if more shock powder is placed on shock powder, it stuns the player while standing on it. It also produces a power signal of 15.
