This wary Pokémon will only appear before people it believes it can trust. Those it comes to view as friends and/or family will be gifted a diamond made through its own powers; these diamonds shine with a bright, soothing light even in the dark.
A sudden transformation of Carbink, its pink, glimmering body is said to be the loveliest sight in the whole world. It sends a soothing aura from its ribbonlike feelers to calm fights.
