Blue's Clues: Mrs. Pepper's Mother's Day (DVD)

Alright, so according to this Tapatalk forum - https://www.tapatalk.com/groups/thewaysofthebluedog/viewtopic.php?p=582#p582, 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: Everyone at Blue's house plans Mother's Day surprises for Mrs. Pepper, all while Joe plays Blue's Clues to figure out what Mailbox's surprise for her is.
