Mission: Crow's Nest
Effect: Head shot a Grunt and witness a Viva Pinata celebration. Confetti explodes and delighted children exclaim!
Instructions:You drop through a hole near a caved-in dead end and enter a long, metal grated tunnel with drones flying in and out of small pipes. Before dropping down another level, shuffle carefully to the edge and look for a green arrow. That's the secret ledge you need to fall on. Then run back the way you came to nab the skull.
