If you head to Mythology Island and walk on Main Street over to the far right, you’ll find an advertisement building for Percy Jackson Camp Half Blood. There are three characters inside: Percy, Annabeth and Tyson. Unfortunately, there’s not a lot to do here besides walk down the path, but you can pick up two very fun special items.
The first is the Cyclops Power. When you activate it and press spacebar, all the normal NPC characters will turn into a cyclops with a single eye. Kind of weird!
The second item is the pen sword, which as you might have guessed is a pen that turns into a sword when you press the spacebar. Actually, to me it kind of looks like a pencil, but I’m not going to argue the point. Get it, pen. point. I kill myself.
