Click below. *Wait *for the entire screen to load up with all four horses and a fence in front of them. Then click on each horse. Make sure your sound is on. *Re-click* on any horse *to make it turn off or turn it back on again*. Somebody did some real wizardry of programming to coordinate this! Try clicking on the horses from left to right then right to left then just one or two at a time ... It's fun and a good stress reliever.
Have fun! Do them in random order for some weird songs.
