If I recall correctly, psyduck aren't particularly bright. Some are even so stupid that they cannot swim (Interesting beind a duck, a water type none the less and not being able to swim. Go figure.) It would be interesting to see how you incorperate this (if you do).
As for the movie itself, great quality, nice use of shading. Good storyline too. Kinda had to laugh seeing psyduck get rejected over and over. Again, well done. I look forward to seeing more of your kwacky (wacky) humor.
