flesh wall tiles

What Feature would you like to see included within TaleSpire?
What does it look like, how does it work, how is it used. Paint us a figurative picture.

 id like to request flesh wall tiles. i have a session in mind where the players get swallowed by a giant monster and they have to explore the insides to get out. its basically like any other building tile but exposed guts. im imagining the asteroid worm from starwars or the gears of war worm that eats cities or even inside the infinite stomach of gluttony from fullmetal alchemist.

What situations would this Feature be useful?
Descriptions, examples, interactions with existing features - whatever you can think of to get your idea across!

 could be used for inside large animals or a creepier version of hell. maybe like chaos or madness biomes as well. depending how it looks it could also blend with other terrain and look like the upside down from stranger things or an oozed city like ghostbusters
