A mud-bath is like playing in the mud but for grown-ups!
You go to a special place where they have a big pool filled with mud. You put on a special bathing suit, and then you jump into the mud.
The mud feels really nice and cool on your skin, like a squishy blanket. You can just lay there and relax while you rub the mud all over your body. Some people even put it on their face too!
After a while, you get out of the mud pool and the mud dries on your skin. Then, you take a shower to wash off all the mud.
After your shower, your skin feels really soft and smooth like a baby's bottom. And best of all, you had so much fun playing in the mud like when you were a kid!
