New download will allow your Pleo to sit and sing apparently. Rick Astley choons unconfirmed. : Tech Digest

As soon as I heard the Pleo dinosaur had an SD card and USB slots in its belly, the potential for after-purchase upgrades immediately sprung to mind.

The latest download, LifeOS 1.1 includes many prime examples of the possible innovations that could be brought to life through these slots, with your little green dino being able to sit for the very first time, as well as change emotions dependent on how much love he receives. In addition, he can serenade you by singing melodies, and may even get sick and cough or sneeze. They're still working on making him poop, apparently...
