[X]DON'T TELL ROSE : ELEMENTALISM.
Telling Rose directly wil result in Shayin being mad at us, as well as potentially the rest of the Estil, and Tomoe stalking us to find out why we, of all people, know so much about magic.
Can we make a copy of the ribbon from a transmuted slice of clothing in a short amount of time, then swipe away the magic ribbon using telekinesis/levitation/teleporation, search for it once Rose notices her hairstyle has become destabilised, and "find" the ribbon we transmuted ? And we could say, after we're a decent way from the mall, too far to go back there quickly, that we like art and the flyer inspires us for a new thing, and can we borrow it pretty please ? Or get another flyer and pull another switcheroo. All that seems a bit mean though, and I wonder what Rose would do if she found out. By the way, what would a mimicry boosting object do to a human ? Would they start randomly shapeshifting ?
How do you think Sasori should eventually wear the ribbon ? Around the neck like a kitty ? Headband ? Bracelet ?
Are sparkcats sentient ?
We should research earth video games and pets once we get back home.
I think Sasori is going to be the animal mascot while in disguise.
