A cute fluffy sheep with yellow fur and purple horn. It run, rolls, eat, sleap, bath above the taskbar, you can grab it. It falls, stuck on open window, and cry because of the fell. It bounce and sometimes aliens capture it. You can duplicate the .exe file and make run them in more than 1 app. It will bounce with each other and make your blog like it were infected by them... Try it!
