In the world of the Yo-kai ... characters sometimes have those days where nothing goes right. They lose their keys. Their pants fall down. 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. There are three Yo-kai medals in every mystery bag, and it's a surprise which Yo-kai Medals are inside. Each medal shows a different character. There are 44 total medals to collect in Series 1 of the Medal Mystery Bags. Blind bag packaging.
