Might not be available on Google Play, given that Youtube is a Google property. More than likely they want people to watch them online, and not downloading them. Youtube download apps are available on: SlideME | Android Apps Market: Download Free & Paid Android Applications
Search for "Youtube downloader" or "Youtube download".
