New Monster: Stone Zombies

Stone Zombie are monsters that inhabit blocks, similar to silverfish. The blocks are found throughout the world and have a similar texture to stone. When broken, the Stone Zombie emerges from the block and attacks. They do 2 hearts of damage but are as slow as regular zombies. Trying to kill them with a sword/ any other weapon takes a very long, and although pickaxes do more damage to them, you can blow them up with TNT easily. But, if you use TNT, it will blow up the blocks, so you can use an item I invented called the Bomb. Bombs are smaller that TNT and are blue, with a string on top. When used, they explode and almost break the Stone Zombie's outer layer. The Zombie will appear to have a big crack in its chest and you can break it with a sword. After the outer layer is broken, it will turn into a regular zombie which is easy to kill.
