Rosie is a type of Big Daddy found in the early levels of the game. If you reach Fort Frolic and you haven't got this achievement dont worry it will take a couple of levels but you will have another chance once you reach Apollo Square.

Everytime you kill a Rosie another will appear shortly after regardless of whether you have collected all Little Sisters for that area. Electric Buckshot and Grenades are the best. If you are struggling early on due to a lack of tonics and good weapons., don't worry. You can always use a Bathysphere and come back to Neptunes Bounty or Medical Pavillion, you will notice how easy they are to defeat in comparison to the Bouncer
