The Amusing Doo-Wop Horse QuartetMake sure your sound is turned on for this one. After all the horses appear, click a horse to make him start or stop his part. Mix and match for unlimited musical possibilities! (Well, ok, after a while it doesn't seem very unlimited).
If you don't see anything above, then you need the Flash player.
Thanks to the Sveriges Television website in Sweden for this fun animation. If you look around on their site you'll find other interesting stuff like the Ko Skating game (requires Shockwave).
