Travel Companion

A travel companion is a Yo-kai that will follow the player around.

Description
Travel companions are simply Yo-kai who will follow the player wherever they go in the overworld. In the first game, Whisper is the only Yo-kai who will follow Nate/Katie everywhere they go and cannot be changed.

In the next two games, even though Whisper is still the primary companion, the player is free to choose any Yo-kai they have a medal of to join him or her. These Yo-kai give no extra effect or bonus, and this feature is more of a decorative one that doesn't affect the story in any way.

Players can also choose to not take anyone with them, and thus travel through the overworld all alone.

Trivia

 * Players can change their Yo-kai by going to their room and then talk to Whisper. You can then choose between him, Jibanyan or any other Yo-kai to join you.
 * To choose a Yo-kai, players must have the actual medal in their possession. NOT just the Yo-kai's Medallium entry.
 * Jibanyan is the only Yo-kai that can always be selected - even when the player no longer has his medal in their possession.
 * Whenever players choose a Yo-kai other than whisper, he'll get upset, and asks the player if the're sure they're thinking straight at that moment.
 * Since Yo-kai Watch 3 has two protagonists, Both Nate and Hailey Anne can have a different Yo-kai to travel with them, and changing the Yo-kai of one does not affect the other's.
