2013 Caldecott Honor Book.
 
From New York Times bestselling author Toni Buzzeo and Caldecott Medal winning illustrator David Small, comes a cool tale about an unlikely friendship.
 
On a spontaneous visit to the aquarium, straight-laced and proper Elliot discovers his dream pet: a penguin. When he asks his father if he may have one (please and thank you), his father says yes. Elliot should have realized that Dad was probably thinking of a toy penguin, not a real one… Clever illustrations and a wild surprise ending make this sly, silly tale a kid-pleaser from start to finish.
