MMHOPH AU where everything is the same but all Sweetypie heart marks glow in the dark. Like some small amount of physically-presenting magic endowed by Mother Pure Heart (that’s another more religious name for the Ruby Pure Heart, I think?) or maybe evolved since the Sweetypies have been exposed to/ encased in its magic for so long. We can assume they’re colorful for magic reasons, too.
So what I’m saying is the Sweetypies are basically magic-radioactive freaks.
