sorry if it is a re-post.
TYPE IN a command at the bottom of the page on the right and see what happens... Sit, roll over, down, stand, sing, dance, shake, fetch, play dead etc. And...it's also very cute if you type in a command that's not recognized...!!
Make sure you type in "Kiss" too, but do it last.
