Tiff's button

Tiffany's button is a smiley face button worn by Tiffany Et. The button has been part of her attire since her introduction and has become the most prominent aspect of her wardrobe. The other three Sapphire kids rely on this button to hold their world together, becoming intensely concerned the sole time Tiffany forgot to wear it. Tiff regularly changes the location and orientation of the button to reflect her current mood, and extenuating circumstances have necessitated similar buttons with different expressions.
