The door stays shut.

"TARDIS! You can't lock me in here forever, you know!" Amy banged against the door, furious, her hair flying as she rapped her fists against the unflinching white metal.

"Come on! When the Doctor finds out, he's going to be... eep!" A jet of ice-cold water had squirted her bottom. "Stop it! You... interdimensional pervert! When I get out, I'll... um, what's that?"

A trapdoor in the ceiling was opening. Amy looked up, and the first drizzle of slime hit her directly between the eyes. It was like lime-green molasses, sticky and sweet-smelling, and it cascaded down out of the roof all over the unfortunate girl, who kicked and spluttered and squealed as she was thoroughly slimed from head to toe. It matted her hair, it drizzled down her thighs, it coated her breasts and left her a sticky, slimy, ridiculous-looking mess. By the time it stopped, Amy was bright red with rage and frustration. She opened her mouth to shriek in protest, and was stopped by the sight of something floating through the air before her. A single, white, fluffy feather.

"Oh, no," she said softly.

The feathers came down in a torrent. The walls transformed into mirrors, so Amy could see how silly she looked from every angle. She was a mess of sticky slime and feathers, clinging to her skin, decorating her breasts and nicely framing her beautiful buttocks. And she was still completely naked, of course.

There was a pause. The air was still. Amy felt like the TARDIS was waiting for something.

"I'm going to kill you," she said, angrily, folding her arms across her breasts. "I don't know how, but I will. You can't do this to me. I'm Amy Pond."

A flash of light, and a puff of smoke. When it cleared up, Amy had disappeared.
