Keep Circulating the Tapes: The show had only six episodes released on VHS in the United States and has zero DVD releases. Thirteen episodes have been released on DVD overseas but the rest of the series is no where to be found. The only places the series can be found are on YouTube and torrents (though most of the episodes are recordings from when the show was on Toon Disney, so some scenes of horror may be edited). The show can now be watched on Hulu however.
According to Maurice LaMarche, Frank Welker was approached about reprising Slimer. However, the recording sessions were at night in order to accommodate the schedules of cast members who worked on live-action projects. Since Welker's schedule was busy enough as it was, he opted to just step aside and gave them his blessing to recast Slimer.
