I have decided to add Ghost.Through out this I will tell you the details First Ghost Would be avabile on normal mode and up. The ghost would act like a blaze, but instead of blazes it would be smoke. If you kill one you get a random type of mob soul the mob soul and and a egg would make a mob egg of that mob. Ghost would be a good/bad find they have 12 hearts(Just like you) And can fly as much as 45 blocks high.But the souls dropped always will be awesome. I cannot post Images But if I could I would.
