This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Senpoku-Kanpoku (Japanese)
Senpoku Kanpoku is a Japanese Yokai monster folklore in Toyama Prefecture. It has a Japanese toad-like body with human-like face. It appears when someone died. It sits beside the body first, then after a week it stands outside the house as a bouncer.
This creature appears as a frog with a human-like expression, and will enter the residences of the recently deceased and settle on their straw mats, living there for three weeks until the day of the funeral, upon which they will kindly escort the casket to the graveyard. The locals regard it as a kami and call it "Tentengotto" with respect, and believe that if its name is invoked during hard times, Tentengotto will symbolically snatch them to safety with its fly-catching tongue.
