Lost Creek Hollow if you want, you can marry

It didn't bother Ashlar that he didn't show the mud, but Sionnach apparently felt differently.  He was delighted just wallowing.  As he splashed his paws he crooned, babbling nonsense that Sionnach likely couldn't understand.  But if she could, it was how neat this puddle was and how cool she was for finding it.

When she bossily demanded that he needed to roll in the grass, Ashlar cheerfully complied.  She did not need to tell him twice.  

Unfortunately for them both (but fortunately for Mona), aside from the bits of grass that now coated him, Ashlar's coat did not take to the green either.  He rolled and squirmed enthusiastically in the mess but did not stain.  The cool grass felt very nice on his back, though, and he eyaaa'd enthusiastically.
