Cute! My daughter has a real mini MM Cob and an acorn one ( whichever model that is ). She's 2 and a half with a full set of teeth and will make a case for the crappiness of the black cob stem material, as she had put some serious gnaw marks on the stems ( no, she was NOT teething at the time ).
She likes to sit around and draw on pipes as long as they have been thoroughly sanitized. Apparently, merely running a few dry cleaners down the stem and shank does not remove ALL the tar, which later gets activated by drool ( we had to wash our mouth ).
I have pictures for my eyes only of her drawing on a 61 Tan Shell Dunhill 120 I had made a replacement stem for. The thing is a basic half bent billiard marked Gp 4 but every bit of a Gp 6 by modern standards. Massive, judging my daughter is really petite slender at 34" tall and 26 lbs.
