I'll have a better idea for that...beer collection event which goes like this:
Hide and seek base so you have to find crates of beer all over the place, than when event ends everyone whos got a create teleports to floran village and throw a party with fireworks and all that shit. From floran everyone is teleported to random citys which they cant leave and they go through the phases of beeing drunk.
1.Buzz, when your body feels like its made out of vibrators and you end up dropping stuff randomly from your inv which is free for everyone to pick up.
2.Stronk guy, when you feel you are at top of the world and you randomly flame everyone around you and you can be attacked(cant be killed just attacked).
3.Lets party some more, when you give adena to people at random because you want more beer.
4.Off, when you are stunned until your beer is out.
