Cookie Monster cake and cookie

This is a little cake (12" cookie) that I did for a client's child for free, as he just got through open heart surgery. He's had a hard little life for a three year old, health-wise, and I just wanted to cheer him up a bit. He loves cookie monster so I came up with this, but made the biggest part a chocolate chip cookie just so it would be easier to eat and share with nurses or whatever. The cookie monster part is cake and buttercream, with fondant eyes.
