This idea is basically just that one scene in Jojo Part 6, but I’m thinking like… way less body horror and way more super cute plant people.
Basically, when your body is exposed to sunlight, it changes to become more plantlike. The more sunlight it takes in, the more of you is converted, until you’re fully a lovely plant folk! You change back at the same rate when you’re out of direct sunlight.
Is it inconvenient? Maybe a little. Does it get harder to resist the urge to just stand still and drink up the sunlight the farther along your changes get? Absolutely. Does standing still for too long run the risk of roots sprouting from your feet and lower legs, tearing through your footwear to burrow into the ground and deliver more nutrients to your body from the soil, changing it even faster? Uuuhh maybe!
… no, no, shut up, it is NOT “Wereplant Wednesday”. Shut up!
