Animation is hard. What if animation was procedural? This is a proof of concept for auto-generating animations. Even the intro isn't animated. While I did draw the costumes, the position and rotation of the costumes are random. This animation is interactive, but it doesn't have to be. you could easily create a way to create a list of positions for arms and legs to follow and record an animation like that. Generating animations (once you have an engine to do so) could be very easy to modify, as you don't have to redraw every frame to adjust a wonky animation, and instead could simply modify the hand or foot of the character. This approach shouldn't replace normal animation, but should instead be used as a way to make rough drafts of the animation. Or something. Really, I don't expect anyone to see this or care.
