It's Final Fantasy, it would have to be something charming, cute or beautiful. Something like a Bard who plays music, our toons would stop to open a locket or music box. Or possibly something we teach a pet to do. If our pets learned to play music and that little swirl of notes like is around the moogle weapons and songbird emote, and a preset song on a pets collar/locket could play maybe? Who knows, maybe if we collect a certain amount of pets they can dawn little instruments and play a preset song as like an emote with them gathered like a little band...you would have to set up the ones you would wish to play in the band and the song you wanted them to play from the music thing back at your Inn/home/FC room...and our toons would wave around a stick before them like a conductor. What do you think?
EDIT: Or following you around in a line like these cats in the video?
