Here are a couple of Daryl's drawings with different characters.
On this first one, you can see a Nyan Cat and some Mario Kart racers. At the middle is Mario and it seems like he's carrying a Bob-omb. Following him is Luigi and some other characters.
On this drawing, you can see Mario, Luigi, Pickachu, Sonic, Knuckles. He wrote that they all found an X-box (green X with a circle). This X-box was also on the 1st drawing.
