The New Scooby Doo Movies Guest Starring Batman And Robin

I watched The New Scooby Doo Movies guest starring Batman and Robin on Boomerang earlier this evening. It was great to see the Dynamic Duo teaming up with the Mystery, Inc. gang. I remember originally watching it in 1972 and have only watched it a few times since then. The Joker and the Penguin were the two guest villains. You can watch the episode in four parts starting here.
