Sometimes you guys might just find a staff member randomly posting in your topic. Often times, these posts will contain spoilers, and inside of these spoilers are goodies! Sometimes they're treasures, other times rupees, treasure chests, and even Lost Fairies.
Whoever is in the topic at the time will EACH receive the reward posted in the spoiler. Or the trap, depending on what's inside of that spoiler. Even if you don't click on it, you receive it (though I'd recommend clicking on it, you know you want to :p)
Well, that's all for now folks! Enjoy!
