"The Social Anxiety monster spends most of it life underground or in secluded sheltered areas, away from human contact. Because of this their skin appears pale and anemic apart from hard plates that serve as as a means of defense.
They will shy away from all contact, even from a fellow monster making them elusive and rarely seen. They are from the same biological family as Anxiety and Paranoia but due to their extreme way of life they have evolved to look quite different."
This is a special monster design, based on my own experiences with social anxiety. There are a lot of design choices to this monster that reflect me and my own difficulties.
