Big Bird's Birthday Party is a Sesame Street "Play-and-Learn" book featuring Big Bird. The book includes a color wheel, which can be seen through a hole cut through each page. It's Big Bird's birthday, and his friends have brought him a surprise gift in six pieces. Gordon, Susan, Oscar the Grouch, Cookie Monster, Grover and Ernie and Bert each give him a different piece, wrapped in a separate color -- red, yellow, green, blue, orange and purple. As the reader helps Big Bird to identify the correct colors, he struggles to figure out how the pieces fit together to make one big present.
