Man, I'd forgotten about this.
Thanks to YouTube, somebody has posted a video of the old FUNTASTIC WORLD OF HANNA BARBERA ride at Universal Studios Florida. As I recall, this was produced at Sullivan Bluth Studios in 1990, and directed by David Steinberg.
This ride ended its run at Universal in 2002, but it lives again and is being re-installed this year at Paramount's Great America theme parks.
