The Yo-Motion Medal design activates a fun feature in the Yo-kai Watch Model Zero (sold seperately)! There are two Yo-kai Yo-Motion Medals in every Yo-Motion Medal Mystery Bag and it's a surprise to see what inside. In Series 1 of the Yo-Motion Medal Mystery Bags there are 30 Yo-kai character medals to collect (2 medals per bag each bag sold separately subject to availability). Kids can pretend to summon the crazy Yo-kai characters from the animated show by placing a Yo-kai Medal into the Yo-kai Watch Model Zero toy. The Yo-kai Watch Model Zero features Yo-Motion Techlogy which projects a short animation of each Yo-kai! Insert a Yo-Motion Medal into the watch to see a mini-animation of that Yo-kai appear on a nearby flat surface and hear summoning sounds that character name and some even play a tribe song! Fans can also scan Yo-Motion Medals with the Yo-kai Watch Land app for more fun and games.
