I don't know how I didn't realize this before but Mamoru's most commonly worn colors are some variation of green, black, yellow and blue
He's wearing the colors of the planet on a near daily basis and if it wasn't clear enough how much he loves the world he lives on, he's got a shirt that spells it out for you.
What a dork.
Anyways happy Earth Day to everyone but especially Prince Tuxedo Mamo. Go tell a rock how much you appreciate it or hug a tree.
really important lesson from Sailor Moon that a lot of people don't pick up on: if you know a girl who's lazy, whiny, immature, and wants to waste all her time playing video games--it might be because she's the reincarnated princess of a forgotten mystical kingdom so show some respect.
