Event ideas

So with the server being quiet and the forums being dead, I figured we need to do more events that will brighten the mood and make the server more exciting. All I ask is for everyone to post good ideas that are simple but fun to do on weekends as events. For example a while ago we did an event where everyone got to enter "The End" and fight the dragon together. Everyone had a blast and enjoyed it. Now I want to know what great ideas you all have that could make the server more exciting.

i think we should do treasure hunts... i used to play on a server that had a treasure hunt plugin but i dont know if it still exists... i think treasure should be a mystery box!

If someone can help me with the LoD, we'll have that to do, as well. Just sayin'. After that is completed, I intend on doing an RPG dungeon out in the wilderness somewhere. If I can.
