Suggestion: Add the Empty Child/Empty mobs

How it would work: The Empty Child/Gas mask zombies in the show are created when a spaceship with Nanogenes falls to earth. How the Empty Child could be implemented is similar to the meteor. There could be a crashed spaceship structure that would generate naturally throughout the world. It could be fairly rare and drop materials for crafting or creating parts of the Tardis like panels, special types of tools and armor, or maybe even used in the process of obtaining regenerations if that is going to be added in the future.  They would spawn from the fallen spaceship and the player would have to fight them to obtain the loot. Instead of the Empty child/Empty mobs dropping items, the loot could also be found in the fallen spaceship, and you would have to fight through to get to it.

How it would benefit the mod: This could add an extra layer of exploration to the mod, and players would have to journey out to find useful items and resources. It would give the players another purpose to adventure out farther in the world and find other features of the mod on their journeys. It could also introduce other loot and items that aren't in the mod yet.
