The "Animals" in the Baby Room

Here are the animals in the baby room. When Claire went back into the room, they panned on the outline of the animals that were on the wall. Paint normally fades when there's direct sunlight on it and this goes to show that the animal posters have been on the wall for a long time and when they were removed, the paint is darker underneath than the rest of the wall. There's no direct sunlight in the hatch, is there?
