Some names have been changed on this video. Susan is renamed "Mrs. Washington" and voiced by Fran Brill, and Slimey is renamed "Squiggly" and is voice by someone other than Marty Robinson.
Little Bird was added into Everyone Makes Mistakes, via recycling illustrations from Big Bird and Little Bird's Big & Little Book (like Everyone Makes Mistakes, this book was also illustrated by A. Delaney), with a running gag involving Little Bird attempting to make Big Bird tell the truth. This was most likely done to help pad out the story to an extended length to fit the running time for video length. Fran Brill also reprised the role of Little Bird for this video.
In the final story, due to the absence of Sonia Manzano in the voice cast, Maria is renamed "Dolores" and voiced by Fran Brill. Similarly, with Jim Henson and Jerry Nelson unavailable to provide voices, the narrator (again voiced by Fran Brill) describes what Count von Count and Ernie are saying, and the Count's bats provide the counting instead.
Some things were ommited from The Exciting Adventures of Super Grover. These include Super Grover's demonstration of "Super Flying," a story about Super Grover vs. the "Hot Fudge Man," and an advertisement starring Betty Lou as a "98.oz Weakling" (parodying the old Charles Atlas ads), most likely for timing.
Emily Perl Kingsley was also involved with the video adaptation work in this release.
