Animal and human running motion animation

This is going to be for a horizontal banner on a website, so the dimensions will be 5:1. The idea is a mouse running on the left hand side of the screen and it morphs into a rabbit running, which morphs into a pig running, which morphs into a sheep running, then a goat running, horse running, then a child running who grows and eventually is an adult human running. Sizes of each animal should be relatively to scale. This could be done in a sketchy style or silhouetted. Color scheme would be white figures on a dark blue backdrop and a red ground. I can send an image with color palates. **Must be proficient in the animation of realistic running. Convincing anatomy is imperative. Would need this as a .mov file or .mp4 file. Short video of less than 10 seconds.
