The Ohumein-Conga (also known as Huge Ming Kong Crabs) are minor enemies in Metal Slug 3, serving as mid-bosses in some routes.
More like a bigger and stronger version of the Chowmein-Conga, the Ohumein-Conga is a giant mutated crab, having a hard carapace that protects them. They are usually seen along with their little brothers but in lesser numbers.
Ohumein-Conga attack by spewing acid bubbles, slamming their huge pincer claws, and charging at the player. Interestingly, the latter attack knocks the player down and makes them lose their special weapon (if any) instead of dying. Their claws have a "friendly fire" effect on other enemies similar to tank threads; their claw slam and quick stab can instantly kill unlucky Chowmein-Conga and heavily damage or even kill other Ohumein-Conga.
In Metal Slug Defense, their normal attack is to split a few acidic bubbles, while their special attack is to charge forward and keep stabbing the floor at the same time. If an enemy gets too close, they will bash it with their oversized claw.
