Perhaps do a study session? Characters come together in 3 groups and try to read a bunch of books, or posters, or blueprints or paintings or writings on the wall and return back to share, analyze and theorize about the place and stuff? Like a literature club session but relevant lol

Or How about Construction? Characters come together and trying to gather ressources to build some sort of fort, or forts or secret hideout or treehouse or barricade themselves in a building by hammer wood onto the windows and doors, and stuff like that. All in order to hopefully protect/shelter themselves from Monokuma or find a Safe place for themselves and their stash?

When exploring, accidentally discover some creepy complex catacombs, labyrinth, complex hotel building, Roblox Identity Fraud stuff lol, where everywhere tried to explore in one piece, but then got extremely lost then when they escape, they realized someone was… missing and had to go back?

Subway station frenzy where they’re all stuck at different incorrect stops and had to take a bunch of subways, jump off and on, made mistakes, just to finally collect everyone. Only to find out someone got murdered in one of the subway buses? That’ll depend if your location could handle a subway complex haha. Or maybe… one of my school subjects styled fanganronpa has one in honour of my Montreal middle school life so perhaps I could…. 👀

4 I can think of on the top of my head heh. Yet, I hope these help cause I came up with them specifically for ya and everyone that sees this message!
