The Playhouse Disney website has a ton of great printable coloring pages. Right now, my four year old is really into Mickey Mouse Clubhouse so he was thrilled when we stumbled upon these. I think that there are about 10 different pages that include all the favorite characters from the show - even Pete! It does require an extra click to use an adobe add on for the print display (but that's also a nice safety stop so your child doesn't go and print 400 pages of Mickey Mouse). :)
