Probably the fastest slug to date, the Ostrich Slug leaves its rider exposed to enemy fire like the other animals, but it compensates with his speed and high jumping ability, able to jump over large chasms with ease. It comes equipped with a 12.6 mm Vulcan, but it only fires in an 180° arc. It's the only animal slug that turns, which takes some time, time that can kill the rider if he/she is not careful. Attacks from above and lobbing attacks are the bane to the rider.
