Two mule brothers were fabricated for a series of Captain Morgan commercials. One brother was top mule, and the other bottom. A fully animatronic mule head was created along with a pair of hooves (capable of crushing a large ice block) for the younger bother. Whereas the older one had a small scale mule body attached to his lower half. Puppeteered via green screen control rods and foot attachments. Which were simply edited out in post.
