Frost Butterflies, theoretically, are not considered intelligent beings.
Even if they aren't Primal Fairies, regular fairies without a Power Level also lack the ability to think. They just follow the Great Fairies around erratically. They can't even count to three, let alone nine.
Being able to count to nine indicates that the fairy has developed a basic logical structure and possesses a bit of wisdom, and can attempt to become a True Fairy.

It tilted its head like a little man made of pixels, smiling at Ian, causing him to squint his eyes.
It didn't look very bright.
