Add a dropdown Menu with the pages already created

I have chosen my theme and created all my pages. Each page is considered a tab to click on at the top of my blog to go to that page, What I would like is: Is there a plugin that once I hoover over the page/tab, it shows a drop down menu of another pages to click on? IS their a plugin pacifically for then.

I’m not looking for a plugin to will add an entire new menu at the top of my page like the Suckerfish WordPress plug in. In addition to my pages already created, it created a entire new row of the same tabs.
