Percy is a Mudwing (from Sally) Seawing (from Poseidon) and Annabeth is a Nightwing (from Mr. Chase) and Sandwing (from Athena) Annabeth does have a CHB bandanna tied around her arm, it just got cut out of the photo. Percy's scarf is there though.
I made Percy half Mud because he is VERY loyal (DUH, it's his fatal flaw) and half Sea because... reasons (GEE I DON'T KNOW!! MAYBE IT'S BECAUSE HE'S THE SON OF POSEIDON!!!!) Annabeth is half Night because she's smart (from both of her parents, but professor Chase seemed very nightwing to me) and half Sand because the sandwings have been involved in multiple wars and Athena is kinda the god of battle strategy and stuff
