Okily dokily, I got it drawn, not colored, though. Too sore at the moment, heh.
Also, I was singing this on repeat while drawing much of it,
Hush little knee don’t you cry.
Daddy needs his sleep, so please, oh please, PLEASE PLEASE LET HIM TRY.
Harrumph! It really doesn’t look too much like a knee, though. 
. I wonder how I could impose a better knee shape, .
