Flamingoes were robots that appear as enemies in Escape from Butcher Bay.
The warden of Butcher Bay Correctional Facility, Hoxie, had two of these robots still guarding the facility. They are old models, and guards think they should have been scrapped 25 years ago. They are equipped with two TF-198 turrets.
The robots have most likely got that name from their long necks and long legs.
