On Annabeth's birthday, she found a plate of perfectly baked blue cookies and a blue birthday cake on her dining table. Beside them, was a note that said "Happy Birthday, Wise Girl" on it.
Annabeth was touched, but she loved Percy even more when she found his alarm clock set to 7am and spotted him at her kitchen sink, trying to rinse tons of flour, milk and blue dye out of his clothes, hair and face.
