Sneaky Little Buggers

Description
"Kill all the loot midgets."

Strategy
This achievement requires you to kill all the midgets that jump out of loot boxes and lockers. The chests and lockers they jump out of are random. The chests and lockers they may spawn in may be the same but the midgets differ from player to player

Trivia

 * One of the Loot Midgets you encounter is Mini Steve, who yells his catchphrase "Heyoo!" in a midget voice upon jumping out of the Crimson Red Chest he is found in.
 * Be careful when opening lockers and red chests in certain areas as the midgets that jump out have very high health and very damaging attacks. On another non-game related note turn down your TV or Computer volume because they can jump out at anytime and scare you a bit.
