Willow is a soft spoken girl who makes a living baking at Papa's Cupcakeria. In her spare time, she enjoys reading spooky novels that she buys at the local Biscotti Bookstore. Willow loves writing free verse poetry and has accumulated quite a collection. Unfortunately, she is quite shy and restricts anyone from reading her poems. The only allowed audience for Willow’s poetry recital is Jackie, her tiny pet tarantula.
Willow has straight black hair that goes down to her shoulders. Clipped in it is a white skull-shaped clip with turquoise bat wings on it. She wears dark-colored eye shadow on her eyelids. She wears a black top with white stitch-marks and turquoise straps, and a turquoise-and-black-striped skirt. On her arms are turquoise-and-black-striped arm warmers. She wears black shoes with silver laces and white soles.
Her Cupcakeria outfit at the beginning of the game is the Cupcakeria uniform with her usual look, but her clip is a red cherry with pink bat wings on it. At Halloween, she is normal, except the turquoise turns orange, she wears white face powder on her face and has put fake vampire fangs in her mouth. The outfit is finished with black bat wings on her back (Pastaria and onwards).
