Boxes are indeed the best in stealth technology, and Clara can't help but to chuckle at the idea of someone sneaking behind their enemy in a box. "You're right, the box is one of the most underrated tool you can use against a hummie."

She kneels down to get a better look at the box, and she them jumps back and her tail smashes into a bowl of candy that goes flying everywhere. "Oi!" Clara is thinking about heading back to the TARDIS to change into something not so cumbersome.

It isn't that she's looking at a cat demon that got her startled; it was the sudden opening of the box. "As for shark, yes, it is a fish and I never tried eating it before. But there's humans who do eat them, so I suppose they might be tasty."
