This sought-after episode was released on video in 1988, packaged with other "Hanna-Barbara Personal Favorites" from the original series and Scooby Doo and Scrappy. Released only a year before stores were flooded with videos of a Batman and Robin episode (which was released to cash in on the 1989 Tim Burton film), this tape is considerably harder to come by and comes in a plastic clamshell case. Just to add to the confusion surrounding the official title of the episode, nowhere on the box or in the credits does it say anything about Shark Island (despite the fact that the titles of the other 3 episodes are listed on the box). The back of the box simply states: "and one episode featuring none other than Sonny and Cher!" Because of the constant changes in video technology, the prints that are currently running on Cartoon Network have a cleaner picture and more clear sound than the print that was released on video -- just something to keep in mind before you shell out your hard-earned dollars for an old used tape.
