"Nooo!" You can see all sorts of things in the pink smoke. Basic facts, work ethic, and memories of toughness all just... leaking out of her head. It all happens pretty quick, but you see the simpler things sliding out after the complex ones. Unfortunately for Lucy, that included words longer than three syllables, anything harder than multiplication and division, and the majority of her common sense/wisdom.
It's... a bit exciting, to be honest, seeing the tomboy's mind devolve into what she'd always hated: the archetypal dumb blonde. Simple and stupid, good for nothing but sex and eye candy.
"I didn't, like, wish for this?" And her voice was changing, too. Not the pitch, that is, but how she sort of fluctuated and presented it. Like it was sort of... breathy and melodic. "Right?"
"Hmph. Serves you right." Marinette grunts, stepping in front you. "Dumb bimbo."
"Huh?" Lucy's lips curve into a simplified smile. "I'm notta bimbo!"
She giggles and sinks into a friendly, curvy, silly sort of pose, where her hips and chest invite your eyes and her hands mindlessly toy with a lock of hair. It's a if she's screaming to the world, "Not too bright" without realizing it.
"Could have fooled me..." Marinette murmurs, and turns.
Looking to you, the last two of the girls seem to wait for guidance, having seen their two friends drastically and violently change.
