Well no, I figured we could just try making up a scenario as we go along. Like say one person says they see a Feraligator, it's foot appears to be stuck in something, but they can't get close to it because Feraligator is angry and throwing rocks at anyone coming close. So a second person says they're using their flute to calm it down. The third person says it seems to be working, but then It turns out the thing Feraligator's foot is stuck in is actually the blow hole of a positively giant Wailord burried underneath the island which ate the ranger that was supposed to set up an exercise here.
Okay, that last bit is too farfetched, but I wanted to give an example that people were not actually going to use. See if you can come up with something you like. I'll post my own version of what is happening tomorrow if nobody steps in before then. Try to challenge each other (this very much includes me), and react to other peoples challenges (same thing).
A battle is fine by the way, that's a good theme to build scenes around. So if you want to go for a battle, write the start of a battle.
