There's also a minigame in there if you boop him in the right places.
Originally uploaded on FurAffinity as a Flash animation, but now ported to rouse, allowing it to run in HTML5 and such. This port was done in part by Sanio.
In the HTML5 version, you can try pressing Alt + Enter to make the animation full screen. It doesn't work everywhere though. Or you can just watch the video version.
And there's a desktop version here. On Windows, you can just run slepp.exe, on Linux and OSX you'll have to build the engine yourself. All of the scripts are included, so you can hack on them if you want to.
