After a long day of work, it's time to kick off the shoes, throw on some comfortable sweatpants and chill TF out.
Well, the horse you are about to meet is no different. After a long day of giving his best friend a ride, he just needed to let off steam.
Clearly, rolling around in the mud is the perfect way to relax after a hard day trekking through the grass and the sun.
Seems like everyone was super careful, the horse especially, and all had some good fun in the mud. You should always be careful around animals, though. However, these people appear to be some very experienced riders and no one appears to have been in danger of being hurt.
