I'm not generally a fan of twin dolls but they seem to crop up. (I have my RS Li and Wu as twins)
Meet Anna Drew Corbitt (she goes by Drew) and Allen Phillip Corbitt.
They are 13 turning 14. Drew is older by 37 minutes and is privately rueful that although both are small and slight, her brother has grown a bit taller than her in the last few months. However, she loves him fiercely and stands up against ppl who bully him. She likes butterflies and has a thing for pumpkin pie. In general, she's a sweet girl who enjoys helping out where she can. She's not a tomboy in that she is quite girly but she is the leader on adventuring trips.
Allen is quiet and shy. He can most often be found curled up with a book if he is not out adventuring with Drew. Even then, he will bring a book along. His favorite foods are desserts, but he will always give his slice of pumpkin pie to Drew.
