Here's a clip from the first cartoon I made -- "The Premiere of Platypus Duck." Made it in college. The music is composed and performed by Parker MacDonell, and that's Parker singing as well. The entire cartoon is 11 minutes long.
This 50-second clip was drawn mainly in colored pencil, with some inked lines on paper. This sequence covers evolution from the dawn of time to the present day, as we see the platypus evolve.
The clip is below these images.
Here's a short clip from the unreleased, unedited and unexpurgated "blooper reel" of the "Animaniacs" episode entitled "Drive-Insane."
