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. This set has two series anticipated (second series available in Fall 2016). Each set includes 3 pages of Yo-kai bios showcasing characters, 3 storage pages, a sticker sheet, and one exclusive medal.

There are three ways to play with every Yo-kai Medal:

1. Imagine summoning Yo-kai by inserting the medal into the Yo-kai watch toy to hear the character's name and other sounds. (Watch and medals each sold separately, subject to availability.) Most medals also play a tribe song.

2. Discover the wacky world of the Yo-kai by scanning the Medal with the Yo-kai Watch Land app.
