On February 13, 2006, parents objected to the book's placement at Rolling Hills Consolidated Library and requested a change of assignment within the library stacks. According to an article in the "St. Joseph News-Press", parents objected to the book's placement in the fiction section, thus insisting that the book be placed in the non-fiction section instead. The book was transferred because "fewer people browse the children's nonfiction section" and "because it was based on the true story of two male penguins that hatched an egg in the New York City Zoo." The permanent move of the book was made on March 4, 2006.
