I was talking with a friend, one time, about our craziest nightmares. One of his (which he actually enjoyed) featured little blue monkeys. One had the face of Muscule Man from Regular Show.
Troubled with artist's block at the time, I decided to draw that for him. We both agreed to call it a special request.
I hope you guys like this, too. (The face does look a little similar to Muscule Man's, but I won't be blatant about it.)
