The Ratticator is, to the people of Strangetown, an unknown assilant who "saves the day" in The Sims 2 for NDS. In actual fact, the Ratticator is the player's Sim in the rat outfit. As the Ratticator, the player can clear goons, robots and aliens. Although aliens can also be eliminated with the water pistol, this method is a lot quicker. The rat outfit is unlocked when the player purchases the Rat Cave as it is located inside. The Ratticator plays a major role at the end of the game, as it is required to be used well in order to defeat Optimum Alfred.
