A New Watch!
Nate, Whisper, and Jibanyan find out that Steve Jaws, the CEO of Yopple quit his job due to people realizing he did not make the Yo-kai Watches but Nathaniel, Nate's grandfather did. Therefore, he was replaced by Mark Shachiberg, who introduced the new Yo-kai Watch, the Yo-kai Watch U. Just when Whisper was about to go to the Yo-kai World to stand in line after learning it can evolve, their found out that there is no official release date for the new watch, which is still in it's Prototype phase, and such, is not readily available to the general public.
In the middle of Whisper's jealous sulking, Hidabat peeked its wing out of its closet, showing the Yo-kai Watch U Prototype. Whisper, surprised asked how Hidabat got the watch. Said bat then showed a picture of Hidabat and Mark Shachiberg in front of Nate's closet, as well as revealing a friendship between the two. Hidabat gave Nate the watch in return of letting her live in his closet, though she also added the Yo-kai Watch U Prototype was much too big for her and it would ruffle her wings. Whisper asked for Nate's opinion on the watch, Nate said it was alright. Whisper was angry at him, getting him to punch Nate into the air over his apparent dismissiveness until Jibanyan thought of using the Yo-kai Watch U to find a Yo-kai, leading them to find out that Nate was just inspirited by Cornfused. Whisper scolded and shouted at Cornfused, demanding them to stop inspiriting Nate, and much to his and Jibanyan's surprise, Cornfused complied without fuss and left. With Jibanyan commenting on how easy it was to defeat him, Whisper asked Nate for his real opinion on the watch, Nate said it was actually cool, and gained Cornfused's Medal out of it. With that done, Nate then stores the original Yo-kai Watch and Yo-kai Watch Model Zero into his closet.
