I just don't get why they give Clara one pink and insist she's in Ballora. While claiming Ballora has pink eyes and that's why Clara has one pink eye. Like where in these is there pink eyes?

How are these pink eyes???

Or like William has purple eyes/or one purple eye mostly because Glitchtrap lives in his head?

Elizabeth has one blue eye because of Baby but Charlie and Cassidy don't have one black white eye to match Puppet, Lefty, and Golden Freddy?
