There's a total of nineteen. I took screencaps of Stephen Colbert's interview about his character in "Monsters V. Aliens". You'll notice that there are two of each icon'd screencap; one is just Stephen's face, the other is Stephen with his character. I just think his character looks so adorkably like him, I had to include him, lol.
Same rules as always:
+ modify in any and every way you please
