Bro I'd leave all the balloons where they are just so they have to bat them around to look at the walls and floor.
It'd probably just distract them from their grading and give them a story to talk about

That's how you set youself up for success.. plus Yoda's probably filthy rich and nobody knows about it.

Oh I just read the descriptions. Apparently that's an old form of wart treatment.
Maybe the Katydid has some enzymes in it's saliva that help to stop the wart from reforming.
Interesting, but disgusting.
