This week on the Super Smart Farm Show, we're heading out to the pig pen to find out if pigs are really as dirty as they seem.

There's no question about it: Pigs love the mud. But why? Is it simply because mud is fun? Or is there more to it than that? Could all that mud actually be helping pigs?

Join host Elmer and Piper the pig as they get to the bottom of why pigs love mud.
