Sly is the Spanish-speaking second-in-command of the bird patrol. He is sneaky and bloodthirsty. He also has a tendancy to swear in Spanish if he screws up. His weapon is a switchblade with a red hilt and red accents on the blade. He is the fourth member of the bird patrol to die. He died when he lost control of his laughter and fell out of the DipTank (all while setting it in gear).
