Pigs need to stay cool in the summer by sliding through the mud. They don't have sweat glands and therefore will overheat without a cold mud bath. So a nice farmer in the Netherlands brought a water slide for his kids to make it easier for them ... not to mention more fun!
Trying to keep cool in the mud can you notice the long yellow thing over there?

“Well, this looks interesting.” This is their own swing directly to the mud

There you go.. look at them

“Now they get to enjoy in the mud all they want, yeah!”

You have to love it when people do somethign this beautiful to make their animal life enjoy and have fun!
