I figured someone would mention that, but I'd dare argue what counts as "depicted sufficiently" considering how obscure PTDs and what not have gotten!
But let's see, Hercules (who in fact has TWO sets of parents!), Simba, Merida, Riley, Aurora, Cinderella may be a bad choice for a Mother's Day pin but it's there!, Ariel (they did the prequel with her mom being shown), Bambi, the Darling children from Peter Pan, Lady and Tramp's pups, Dalmatians and their pups, I'd argue for Aristocats being that O'Malley becomes their adopted father, Mulan, Pacha and Chicha's kids from Emperor's New Groove, The Incredibles, Tiana, Rapunzel, the girls from Frozen (if they're gonna make a pin for Cinderella's dad they can do the king and queen of Arendelle!), Arlo, Dory (now), Judy Hopps, Moana?
