Ideas for new specimens

If there is room for Specimen types I have a couple (or just make a mod for them later on in the future).

Blister or Bulbous:A Specimen that walks Exploding Little spider like Creatures that Skitter around attacking the player,Now there isn't just the Crawler to worry about.

Vapor: (similar to the Stalker)Wisps of smoke or steam that trail from the specimen before or after Cloaking(or attacking).
