"Hm..." The queen slowly starts to grin. "Candy, could you come over here? I wanna give you another gift."
"Sure, cutie~" Candy wanders back over. "Is it a kiss?"
"Nooope." The queen sticks out her tongue in a tease, and puts her hand on her head. "Guess again!"
Candy gasps as the drain starts. "Is it another set of smarts?!"
"Nope!" The queen giggles and smiles as Candy's higher education vanishes.
"Darn." She pouts, but bounces right back. "Um..." Her IQ level begins to fall next. "Are you gonna give me, like, a pretty new hair color?"
"Not bad." The queen feigns approval, and watches as the bimbo does a happy little dance in place. Her overall intellect isn't anything truly impressive anymore, and, due to her bimbo mannerisms, most people wouldn't be able to see her as anything but eye candy anyway.
"Buuut~"
"But?" Candy frowns, her jaw slackening a little as her brow furrows cutely.
"Not quite!" The queen cackles a little, and stares deep into the girl's simplifying eyes.
"Oh, shoot." Candy's shoulders sink. She scratches her head with her hand, but doesn't seem so quick anymore. "Uuuuuuhhhh..."
"Keep guessing!" The queen giggles and giggles, feeling her feelings rise and rise for the dumbed down ditz. "If you guess, I'll give you ANOTHER PRIZE!"
Candy perks up at the mention of a prize. "Okay!" And then she puts her fingers to her temples and starts to groan and physically strain her brain. "Erm...!!"
Wanting to see what she can come up with, you note her IQ at 84--a bit lower than what she'd started at--and wait.
