Booker is a comedic bulldog found in the Animal Crossing series. He, along with Copper, have been hired as police officers for the village, though while he means well, he's considerably a foolish character who gives in to almost anything. He's extremely apologetic, and doesn't quite explain clearly what he wants to. In Animal Crossing, he guards the village's lost and found, though he'll blatantly give away anything no matter how outrageous it seems. In Animal Crossing: Wild World and Animal Crossing: City Folk for the Nintendo DS and Wii, respectively, he and Copper guard the front gate, and once again he runs the lost and found, though will also explain, in some sort, what events will occur in your village.
"The guards stationed at the town gate through which travelers come and go. Copper, who's on the right, is in charge of traveling via Nintendo WFC, and Booker on the left runs the lost and found. Booker's a cute fellow who's known for his indecisive manner...maybe. Copper's diligent, dedicated, and always ready to lend a helping paw."
