Last week when we woke up in our rooms there were some really, really tempting cupcakes next to the beds. But if you ate yours you got a curse. Some people turned invisible and had to cook for everybody, some people could only lie or tell the truth, some people spat up gold coins and gems whenever they talked. That kind of thing.
From what I've seen and been told, though, it all 'resets' after seven days, and then something new happens.
