"Someone is trapped wearing a plushsuit"
A non-specific character is inside a plushsuit, and only the head pops up from the plushsuit mouth. The concept is somewhat unstable, and the efficiency of this one depends of what kind of character you want to be the plushsuit, sadly I can't define the host with accuracy for now, but of you can do some prompt acrobatics probably you'll can obtain something.
The strenght works fine at 1.0, but if it doesn't work just increase it to 1.1 - 1.2, just be creative.
