The Yo-Motion Medal design activates a fun feature in the Yo-kai Watch Model Zero (sold separately)! 

There are two Yo-kai Yo-Motion Medals in every Yo-Motion Medal Mystery Bag, and it's a surprise to see what’s inside. 

In Series 4 of the Yo-Motion Medal Mystery Bags, there are 30 Yo-kai character medals to collect (2 medals per bag).
