And Tango Makes Three Justin Richardson (Author), Peter Parnell (Author), Henry Cole (Illustrator) Based on a true-life penguin family living in New York City's Central Park Zoo, this is the story of Roy and Silo, two male penguins that cuddle and share a nest like the other penguin couples. When all the others start hatching eggs, they want to be parents, too, and bring an egg-shaped rock back to their nest to care for. A watchful zookeeper decides they deserve a chance at having their own family and gives them an egg in need of nurturing. A daughter, Tango, arrives soon after and the three can still be seen at the zoo today. [Grade Level: Pre-K - 3]
