Alright, I got a twofer for ya.
1. The Tickler from Johnny Test. This one should feel obvious consider the dudes name, but I can see why no one would take a second glance. But this one's not so much about attractiveness. But the potential. So many ways you could go about it. You're a test subject, willing or otherwise. Made to endure his newest inventions or experiments. One day he throws you in a room filled with robotic arms that pin you to the walls and floors. Firmly planting you while they tickle you to shreds. And in the same day, he locks you in a cage with a genetically modified tickle monster. Next your feet, locked into stocks and tickled for hours on end. Meanwhile rays from a "Tickle Gun" is fired off at your exposed soles.
And of course, you could always reverse it. But not with him as a Lee. But by helping him secure other Lee's. And it could be ANYONE, you want. That one teacher who always put her feet up during tears? Lock her ass in the stocks and set that ray gun to full power automatic. The bully who constantly teased you and just makes your life hell? See how his attitude changes after a couple hours locked up with the tickle monster. How about the person of your dreams, trapped in the room with the metal arms. While you watch in ecstasy on the other side of a 1 way mirror. Like I said. Potential.
2. And this one is very different lol Just like. Smurfs. Not necessarily just Smurfette or any specific one actually. Like just having one that I found somehow locked away. So anytime boredom strikes, I go to wherever it is and wreck the thing. I make little stocks for its feet and just watch it squeel as I slowwwwwly drag the longest feather I can find back and fourth over it's soles. Have it spread it eagle on a piece of sturdy cardboard and just envelope its torso with a make up brush. And if I were mechanically inclined, I'd love to lock it up in a contraption like the one from this Achilles piece.
