The bustle of the crowd is waning and the zoo is quieting for the night. The polar bear picks up the ball and dribbles onto the court; the nightly game begins. A frog jumps up to play one-on-one and then a penguin waddles in to join the team. Count along as the game grows with the addition of each new animal and the field of players builds to ten. Three zebras serve as referees and keep the clock, because this game must be over before the zookeeper makes her rounds.
