Jim Henson productions collaborated with Nickelodeon Television and characters from famed author Dr. Seuss (Theodore Geisel) in 1996 to create the series "The Wubbulous World of Dr. Seuss." Henson populated the program with puppet versions of many famous Seuss characters. The series fostered spin-off merchandise, such as children's activity books, filled with pictures of the Seuss characters and their antics. This example features many different Seuss characters.
