The Flamingo is a weapon found in Warrior Within.
This weapon is a secret weapon. It is a light weapon, so it will strike fast and hard. It does two times the damage while counter-attacking and is indestructible. With one hit, it knocks down enemies, leaving them vulnerable, and also knocks them down when thrown. The White Glove shares these properties. It is found in the Garden Tower while in Present.
After you obtain the Scorpion Sword, return the Garden Tower. Climb all the way up to the top of the garden hall, and use the portal to return the the present. Once in the present, (where the Dahaka throws you down the hole as the sandwraith) clime up the ladder and across the room using the ropes. To the left walk through the rubble and hit the switch on the wall the causes a shelf to move forward. Once you clime up the shelf and onto the beams, work your way across the ledges down to that small platform, there is a weak wall that can be broken, and the flamingo is within.
