Rockabelly "Harao-dori"

Rockabelly is a Yokai of the Eerie Tribe. He makes a funny face appear on your stomach and an irresistible urge to make it dance. When he inspirits you, a weird drawing will appear on your stomach and you'll suddenly start flaunting that face around through belly dance. This Yo-kai is responsible for the, "This is getting really annoying!", phenomenon. Like when a crazy fad suddenly becomes stupid and boring. (Source: Yo-kai Watch Wikia)
