Book Description
The world's leading toy manufacturer gives each toy it creates a tiny, computerized brain and a unique personality making for some seriously awesome toys. But sometimes there's a faulty toy . . . Dan is a "Snugliffic Cuddlestar" bear--he should be perfect for hugging. But because of a malfunctioning chip, Dan is so strong he could crush a car. Thrown into the rejects pile, he meets Arabella, a "Loadsasmiles Sunshine" doll, who has a very short temper. Soon Dan, Arabella, and Flax (a custom-made police robot rabbit) are recruited by the head of the toy world exactly for what makes them unfit. And their first mission is a doozy: to protect a senator's eight-year-old son from being kidnapped. With black-and-white illustrations throughout, this hilarious book has reluctant reader appeal written all over it.
