Shadows and white shapes. Without seeing the shadow maker - we can still guess what shape-shifter is interdicting the light. The only reason that we don't loose the shape of things which are covered in shadow is because the shape-shifter has allowed just enough light to break through. These eggs look very reptilian in this presentation - don't they? Was that apparent at first look by you? Or did I point it out? Funny how the power of observation works in the trained mind. Omelet anyone?
