After Phil's suggestion of my kite needing more movement, I had the idea of characterising him similarly to a dog. The emotions could be shown though posture, perhaps in the days where it is raining he could do humorous dog things like scratch and clean himself. His ribbon could move around like his tail. I know it's for only a 1 minute animation so just a few small things like that could cover movement.
Some people suggested Beauty and the Beast (Disney) taking a look at the footstool as a dog.
