In the "Even Yo-kai Get Sick" Yo-kai Spot in Nocturne Hospital one of five Yo-kai will appear: Alloo (who will fight you), Grumples (who will give you a Soul Tea), Ol' Fortune (who gives you a bitter medicine), Tattlecast, and Skranny. If Skranny appears, she will fight you and can be befriended through normal means.
Her English name, "Skranny". is a portmanteau of the words skeleton or skeletal, and granny, a term of endearment for someone's grandmother. Her Japanese name, "Dokurobā", is a combination of (Japanese: 髑髏,Dokuro, "skull"), referring to her Día de Muertos-inspired visage, and (Japanese: 婆,Bā, "grandma"). It's also a variation of "Bakurobā".
