Basically you pick them up using square or whatever the XBOX button is, then the next time you teleport, you press square/XBOX button whatever that is, on the projector then it tells you a little bit about the story line of the zombies, I think theres 4 or 5 rooms and they all say something different (to see them you need to go back down to the theatre and it will be on the big screen/big thing hanging down in the middle of the stage, and you can play one at a time, and pick up only one, then play it, and pick up another one)
