In the "Even Yo-kai Get Sick" Yo-kai Spot in Nocturne Hospital one of five Yo-kai will appear: Alloo (who will fight the player), Grumples (who will give the player a Soul Tea), Ol' Fortune (who gives the player a bitter medicine), Tattlecast (wich will also fight the player) and Skranny. If Skranny appears, she will fight the player 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".
Her Spanish name, "Esquelelleja", combines "Esqueleto" (Skeleton) and "Cotilleja" (Tattletell).
