I can't seem to find any episodes anywhere but, then i bought a powerpuff girls DVD and the "Sheep in the big City" first episode was the bonus cartoon. Every cartoon network powerpuff girls DVD or scooby doo DVD has a bonus cartoon. From Courage the cowardly dog, Time Squad, What A Cartoon!, Sheep in the big city, Ed, Edd, n', eddy, Dexter's Lab, and many more.
On Powerpuff Girls DVD/VHS "Powerpuff Bluff"- Bonus Cartoon- Sheep In The Big City Episode 1
