I didn't get an event for the last trivia on whether I got it right or not...so how do I know? I'd check the blue building but it wouldn't help; I don't remember what I had before. ^_^;

If you didn't get an event, it's possible your answer didn't go through. You should always submit twice, just to be sure.

Submit your answer twice? o.o It doesn't let you, I didn't think O_o

Edit: And...the prize is in my inventory...so I obviously got it right. :)
