Those legs are mesmerizing, ngl. I love how the entire animal moves when it walks, too. It's not just the legs, but the head, neck, humps, tail, the whole body. Even if it's just a slight jiggling of the edges of each hand-drawn panel, it still helps lend a lot of credence to the movement. It makes it feel more full and natural than just a body hovering along, perfectly still, with four legs wagging.
I dunno, this is super charming and I really enjoy watching it go. I hope it can still find uses outside the film! I think it's really lovable!
