Mouse roll-over "Tool Tip" how to do it??

-- url of the page page I want "Tool Tips" on -- : x-raynews.com/index.php/products/product...ebraska-subscription
-- HikaShop Essential version -- : 2.2.1
-- Joomla version -- : 2.5.14
-- PHP version -- : 5.4.17
-- Browser(s) name and version -- : Most current versions of IE, Firefox, Chrome, Opera, Safari.
-- Error-message(debug-mod must be tuned on) -- : No error message. Just trying to find out how to do it.

Perhaps there is a 3d party extension to do what I want?? See attached png file.

Thank you for your time.
