So there's this animated show called Victor and Valentino that featured some ABDL content in an episode titled "The Boy who Cried Lechuza." The titular Lechuza is an feared legend said to abduct children she hears crying. The Lechuza actually turns out to be an odd yet motherly creature who, in a sequence of events, abducts one of the protagonists, fully intending to "pamper him." As he's taken to the nest, he meets three adults who were abducted as children, who are fed and diapered by the Lechuza. They seem pretty content with their lives, with one woman appreciating how they get diaper changes often. I can't seem to link pictures, but I always appreciate diapered women in media, animated or not.
