Jack o' lantern

The Jack O' Lantern is an Easter Egg in Halo 2. It is easy to view, as you simply need to destroy a Scorpion, and stand on either the upturned turret or the main body of the Scorpion. Look at the gears on the connecting section, and there is a Jack O' Lantern drawn in blood. It may help to turn on your flashlight.

Snag — The Jack o' Lantern. It is very difficult to make out the lantern.
