I rented a digital copy of Potty Time Plus and added a full content rundown on the wiki.
I had not seen Elmo's Potty Time before, so it was interesting. I'd say the video is just okay (even if Frank Oz performed Grover in new content here). Have any of the segments been used on the show? The wiki doesn't list firsts for those, some kind of look early 1990s but I am not sure and I don't recall seeing any of those. Seems odd they would create so many new animation and film bits just for the video (I think Being Green did the same thing).
I'm guessing the Elmo's Potty Time video is unaltered, complete with end credits, and then we get the extra stuff (and a new set of end credits), seemingly a second home video compilation. While the main feature was made before the switch to HD, everything added is in high definition widescreen. As I was adding to the wiki, I found that many of the segments that follow the street scenes first appeared in said episodes, which gets me wondering if these should be counted as heavily edited versions of full episodes (to just include the segments pertaining to the daily routine of the street story). That is in addition to some web-created content (including three Sesame Studios shorts) and a handful of inserts that I think debuted on the show (such as Elmo and Abby imagining brushing their teeth and Elmo showing a checklist of his daily routine while singing "Rock a Bye Baby").
I figured we wouldn't get any classic clips (would have been cool to have Breakfast Time, or Ernie plans a bath, or Kids Just Love to Brush), though it is a shame it doesn't have any additional fullframe bits outside of Elmo's Potty Time.
Interestingly, the Muppets trademark credit in this is now listed as going to Disney Enterprises, when previously it was Muppets Holding Company or Muppets Studio. Not sure if this trademark credit has been used on recent Sesame Street stuff, though I feel like for the last seevral years they had not been using a trademark credit for the Muppet name (the last few Sesame Street DVD releases that feature Kermit content actually don't list a trademark credit for the character.... I should check back and see if those do still have a "Muppet is a trademark of...." even without a Kermit trademark).
