I agree with Manda on this. Kermit is more well-rounded because he has all emotions, and isn't always so "perfect" as they try to make Mickey. He was just too sweet in "Who Framed Roger Rabbit?" and in nearly all films. After Steamboat Willie and other earlier films, he had a small mean streak, but not much.
I made Muley mischevious. My cartoon character, puppet character is sweet, mean, flirtatious, playful...all things 'humanly' emotional.
I think Mickey misses out on that, unfortunately.
And Cory, I have been holding out on this information for a long time, but I DID meet Kermit the Frog. We had coffee and some kind of chocolate covered something crunchy when we were all at MFest.
Then my alarm went off and I woke up.
