Oh this, I didn't make it clear. In principle, Japes on each floor have the opportunity to pick up a balloon without leaving the lobby before. Only one balloon per floor.
I don't really think that's a good Idea then, on principle; I mean, if there was one balloon per room, and if you somehow avoided taking damage, you'd get goodies. I say somehow because you are kind of missing out if you don't let yourself take damage.
