Sesame Street X The Backyardigans

This description is a long one, so read ahead.

This crossover replaces Sesame Street's partnership with Toys and Colors in my timeline despite taking place 17 years prior. It was such a low blow for Sesame Workshop they would partner with YouTube channels actively harming children's brain development, yet they also partnered with The Wiggles and Super Simple Songs, which are not brainrot.

It was made by Sesame Workshop and Nelvana in 2008 and only given to the staff that worked on it, so it was lost media for years until it was leaked in 2025 (when the Toys and Colors collaboration would've been in real-life). It is similar to Mickey + Bluey. (which uses Mickey and friends in the classic 2D style since the Mickey preschool shows don't exist in my timeline)

In it, Elmo is on Sesame Street, welcoming the viewers, when he notices a portal behind him which he is sucked into once interacting with it. Once in this new world, he finds himself in the Backyardigans theme song, where he is noticed by the fab five (besides Disney's, that is) before they sing the theme song. The "we've got the whole wide world in our yard to explore, we only find things we've never seen before, that's why every day, we're back for more with your friends..." lyrics are dropped, and replaced with the Backyardigans saying the names of Elmo's Sesame Street friends, in this case, Abby, Telly, Grover, Rosita, and Zoe, as they come into the scene, before the camera cuts to Elmo with The Backyardigans in their title card, which removes the Nick Jr. logo and Janice Burgess' name credit. The style from the Sesame Street home video, Elmo's Alphabet Challenge, is used in this crossover.

"Pablo and Elmo" was a search on Google when I searched up Pablo's name not too long ago. This makes me wonder why there wasn't a crossover between Sesame Street and The Backyardigans, despite them being on different networks/blocks (those being PBS KIDS and Nick Jr., respectively), as these are both children's shows with animal or creature children using their imaginations and having musical adventures often with audience participation, and both shows were on the Nick Jr. channel's former name, NOGGIN.
