2 rockets chasing each other in a city

Hello everybody,

I remember a demo back from the good old days in which two rockets in cartoons graphic were chasing each other in a city. One red rocket was chasing a green rocket with all the good Road Runner charisma like sniffling, trapping and even a red traffic light forcing them to stop. It was no game demo, but just someone showing a nice cartoon. I think it must be made around 1991 because I got it together with the famous Odyssey
from Alcatraz.

It was quite funny and I would like to see it again. Does anybody know its name and where to get
