That reaction is perfect because that's exactly the idea it's based on! So, I guess I did my job :D And yes, in this game, knowing the worst scenario of this slumber party would make me want to stay home FOR SURE haha.

There are three endings total! You're missing the second ending (good job on finding the other two!). As for how to get it, the comment on Brandy's computer said you shouldn't put your own hair into the charm that's described in the blog post . . . but it never said you couldn't.
Hope that helps! Thank you for playing and commenting!!
