We had a short clicker training session today; the goal being to have the pony put all four feet in the tub. He's had his two front feet in the tub several times previously.
Then we asked for the third foot to step into the tub.
He had a little problem figuring out how to keep all four feet in the tub. When the fourth foot (the back foot) came into the tub, the front one went out, followed by the other front. He kept the back feet in, and you could see that he was trying to figure out how to do this. He lifted his front feet and put them back into the tub.
