Check out the showers.

"Alright, Daisy," you say, as you walk into the elven shower room. "Operation Buttercup. You know the score?"

"Sorry?" says Banti, who's walking right beside you. The three of you are invisible, of course, and your magic has made it so the showering elves can't hear you talk. "What's Operation Buttercup? Did I miss something?"

"Oh, we used to do this all the time back home. It's just a way of embarrassing a shower room full of girls. You'll like it."

"Well, as long as you're not embarrassing me." Banti rubs the stamp on her butt. You get the sense she's glad to be invisible. Though you can still see her, of course. "Do I have to do anything?"

"Just stand there and watch."

You look around the room. A whole elven cheerleader team is in here, scrubbing the sweat off their beautiful purple bodies. The team captain is an athletic, pale girl, her skin so light it's lavender, plum-covered nipples capping small breasts and a dusting of curly violet hair between her legs. You've already checked her out from head to toe, invisibly, along with all the other girls. All that remains is to embarrass her.

"In position, boss," says Daisy. She's gathered up all the girls' clothes and towels and thrown them out a window, without anybody noticing. Now she stands by the doorway with a big bucket of glitter.

"Well done," you say, giving her a professional nod. "Actually, Banti, could you twist that valve for me?"

"Why? What's it do?"

"Just trust me. I'm an expert on girls' shower rooms."

Banti shrugs, and twists the valve. Immediately there's a chorus of shrieks, as twelve shower heads begin to blast ice-cold water down on twelve nude elven cheerleaders. It's your time to strike.

You snap your fingers, and conjure up an illusion of a huge terrifying ogre. "Rrarr!" it shouts. "I'm the Shower Surprise Ogre! Get out of here right now, girls, or I'll snatch you up!"

"What?"

"Eek!"

"Oh, no!"

The girls stampede for the exit, surprised and terrified. Some of them look around for their clothes on the way out, but of course the clothes are all gone. When they see that, one or two of them turn back. You make the ogre stomp towards them, and they squeal and flee again. Daisy is standing by the exit as they run, throwing glitter into the crowd, making sure they're covered from head to toe in the sparkly substance. And nothing else, of course.

The girls file out into the gymnasium, where a first-year gym class is going on. At the other end of the hall, the boys' basketball team is practicing. At first, they're too confused to understand what's happening. Then, they look down at their bare, sparkly bodies. Then, they look up at the boys and the gym class, who are watching the girls with huge smiles on their faces.

The shower-room door slams shut behind them.
