That's similar to the other possibility I mentioned, but I had Cho Li transforming to play the part (like Iruka did to the rookie 9). Whether it's her or some others, it would definitely give more of a challenge to the test. I assume if it were others, they would be fellow jonin that Cho Li brought in to help (or ask if they want to torment some genin :P).

When would they attack? (at night, the next morning before they leave, etc.)

What would be the lesson for the test? (The bell test was teamwork) The 'spend the night' part would probably be just survival in general. What about the attack? Which lesson would be the main point of the test?
