In FNF: Melodies and Spookeez, William is, in simple terms, Pump without his costume. He is a 7-year-old boy with curly brown hair, deep-brown eyes, and fair skin. He is rather shy and introverted, but just as cheerful as Beverly (Skid), and he loves Spooky Month, Halloween, and all things spooky. He adores Susie, his big sister, and her pumpkin pies. He is Skid’s adoptive little brother.
