The SpongeBob SquarePants doll is based on an animated TV series, created by Stephen Hillenburg.
It was created for Nickelodeon, a cable and satellite TV network.
The primary idea evolved into adding several related products such as home video, comics books, films, music, t-shirts, posters, video games, theme park rides and of course dolls.
SpongeBob dolls were a success and gained popularity, especially in Japan.
