Have fun and guess the cartoons that were from the beginning of Nicktoons to about 2010. Obviously, some cartoons went longer than 2010.

Some of these shows may not have been known as much as others, but they were still Nicktoons.

(P.S. Sorry if there are any mistakes in the theme songs!)

(Also, I do not own any rights to any of these theme songs, all of the rights go to the respected owners.)
