Forum game: Guess that mob.

Baby Typhoons.
Totally matches everything - wings are the normal Typhoons, they can still attack, can't break out cause in a shell (also makes it unsafe), high up in the sky.
Only thing missing is that I never imagined those maps as cold, but that can easy be counter-argued by saying it's cold for an undeveloped being inside its shell that can form thoughts.

You read my thoughts you won again. Didnt think anyone would guess it this quick though.
I'll come up with a fifth one soon thats a lot harder.

Mob number 5
I bet nobody will see me like this. I'll just sit here and wait for someone to pop up and sneak attack them.
I have to say though that there might be a flaw in my disguise, one assasin was able to throw a ninja star and hit me....
It still hurts.
