In the world of the Yo-kai . . . characters sometimes have those days where nothing goes right. They lose their keys. Their pants fall down. They fart in a crowded elevator! Chances are, a Yo-kai is to blame. They're everywhere, causing daily annoyances, and they're invisible except to the characters who have befriended them. Kids can add these Yo-kai character and storage pages to a Yo-kai Watch Medallium Collection Book (book, refill pages, and medals each sold separately, subject to availability) to learn more about the Yo-kai in each planned series of medals and help organize their collection. Each character page shows a Yo-kai image, and includes information about their tribe and background information. Each set includes 3 pages of Yo-kai bios showcasing characters, 3 storage pages, a sticker sheet, and one exclusive medal.
