The Mario world princesses (including crown transformations) as sextuplets. They were all born blondes, but eventually sought out individuality, and made themselves look different.
1st born: Rosalina, the fashion icon and the responsible one...as long as you don't call her "Rosie". She hates that.
2nd: Bowsette, the punk rebel. Born with a tail, she's used to being picked on and being angsty. Her sisters would never go that far.
3rd: Daisy, the neutral optimist. Her optimism is like the last bowl of porridge: not too much or too little. Just right.
4th: Rain, the energetic wild child. She loves drama and conflict! She CRAVES it!
5th: Peach, the girly-girl. Eagerly waiting for her knight and shining armor. But sadly, life's not a Disney movie.
6th: Boo, the quiet goth. She's friendly...mostly.
