First, make sure 4 ghosts are on the screen. Then, move a little bit to the left so Sue (The purple ghost that appears if you stand around, go left, etc.) appears on the screen. Eat a Power Pellet (The Power Pellet MUST be on the screen with the 5 ghosts), then eat all ghosts except for Sue. When you have eaten 4 ghosts, eat Sue (Sue MUST be the fifth ghost eaten). A small Pac-Man icon with an L will appear. Collect this item and you will earn additional points and the time limit icons on the top of the screen will be completely refilled, giving you more time to search the levels.
