Yeah, But you could also add them in like dueling class when you do the hunger games. They could be up a tree or something. Or in classes where you don't have to sit down. Like Wizard's PE, Dueling Class or maybe in the middle of the flying class track.
It would be fun if there were hidden chests in classes. So you could also get them there. They should be well hidden. It would be a nice addition to the server.
