Book is many books at once! She's a dictionary, a journal, a Hand-Powered Hand-Powered Recovery Center Creator user manual, and a guidebook for IDFB. Book and Ice Cube have formed what Book believes is an inseparable bond, as Book always protects Ice Cube. She's also formed a close relationship with Ruby, but she won't go as far as to eat Ruby's Yoyleberries. She can either be upbeat and joyful, or mean and manipulative. Her catchphrase is "I'm a dictionary, and you'd better believe it!"
