Here's another in-universe show for the Sprout universe. The reason I put quotations in the title was because this is more of a video series. It's been around for so long and every child in the Hills has watched their videos when they were much younger.
Baby's World is a company that produces CDs, books, toys, flashcards, and most of all, video releases. They have a few plans that parents can buy online so that every month, they can have the company's latest products delivered straight to their doorstep. Families can have a plan signed up to get Baby's World products delivered to their house once a month every year. As I was saying, the videos are the most popular part of Baby's World, having been produced since the home video boom started in 1985. They have everything you hope to see in a child development video - classical music, a few songs with lyrics (be it original or traditional) here and there, stock footage, puppets, animation, and clips of real kids.
Baby's World is a favorite of Hills of Sprout parents, whose children watched their videos, all the way back to when Mossi and Adam were tots, and appreciate the impact it's had on them over the years. See if you can guess what property THIS is based on! (And before you ask, no, the "videos are bad for babies" thing doesn't exist here, as I'm honestly sick of it)
