The red & green lazers turn off when you zap the RED mirrors, if you direct the mirrors so it deflects the lazer beams a certain way it turns some off. But you have to work out which ones to change, I got killed so many times working it out. But now i'm really stuck getting the fifth egg, it seems to get harder. And the secrets are hidden under a pale blue dome shape. Hope this helps you. Now I wish someone would help me !
