"Defeat Midgemong" is an objective in the sidequest Symbiosis in Borderlands 2
Walkthrough[edit]
Midgemong will charge out from the room, run along the side of the level you are on then jump for one of the rooftops nearby. He will then turn and face you, guns at the ready. Midgemong will jump around the area a lot from the walk-accessible right onto the nearby rooftops. It is easiest to take out the Bullymong first, the Warmong. This will just leave you with a variant of a Badass Midget. He will just walk around with his twin assault rifles shooting at you. If you hit him with a headshot, this invokes much the same reaction as you would get from a Goliath. He will enter a rage and start attacking other bandits as well.
