This is a charming Disney short called “Off His Rockers”. I remember seeing this in front of “Honey, I Blew Up the Kid”. It’s one of the more successful early attempts of blending CG and traditional animation. To help put the technology in perspective, this was released 3 years before Toy Story. The CG might be a bit simplistic (by today’s standards) but that didn’t prevent Disney from instilling a believable and wonderfully captivating personality in the rocking horse.
