Evil duck

On the multi-player map Isolation, go to the Flood cave where the Ghost is located. Go in front of the Ghost, look up, and walk a short distance slowly. You will see a big smudge on its face, but look carefully for the duck's body. You can partly see its face and the horns on its head. This is related to the picture in Zanzibar in Halo 2.
