Playable headspiders and transposed particle fields

[Lady Birb]

With all the playable critters we have been adding recently, with the wizards Polymorph spell and the changeling's handspiders, I suggest that we add a bit to that:

A. When a changeling releases a headspider the hivemind master will take control of the spider, where it will behave like a handspider, but with gnaw replaced with crawling down the victim's throat.

B. If you get turned into a transposed particle field from wearing the obsidian crown for too long, you would be able to play as the field and go around the station as a spooky science ghost.
