During the development of my prototype/demo, I have to narrow down and develop some of the characters that I created for my school project.  One of these characters is the antagonistic Yokai : Waniguchi.

In the game, you encounter many Waniguchi as antagonistic illusions created by the kitsune to harass and annoy the other inhabitants of the Cavern and Tunnels. 

Waniguchi are Tsukumogami , man-made objects that gain life after hundreds of years or become possessed. Waniguchi are specifically temple bells which happen to look like crocodile jaws. 

Waniguchi is actually the name of the bell but it also is the name of the yokai in folklore. 

Beacuse of its wide-gap, it looks like a crocodile's mouth and as such in folklore, this yokai is depicted as reptile like with aquatic features. Although my Waniguchi is more reptile like than aquatic. 

You can learn more about Waniguchi by visiting Matthew Meyer's Yokai.com where you can learn more about other kinds of Yokai.
