Magenta's Super Sleepover

Alright, so according to this Tapatalk forum, according to "Anytime Playdate", which is a 2000s book about preschool shows, it was announced that when Angela C. Santomero and Alice Wilder started production on Super WHY! on PBS, they struck a deal with Nickelodeon, home of Angela's previous show, Blue's Clues, to produce movie-length episodes of the show, which were cancelled in real-life but exist in my timeline as "family specials" (think Shining Time Station's) and are each based on a Blue's Clues book, except with the addition of Joe, starting with this one:

Summary: Magenta is having a sleepover at Blue's house, with Tickety Tock as the chaperone, so Joe plays Blue's Clues to figure out what they should read about for the bedtime story, but Blue has a nightmare about it afterwards.
