The Best of Nicktoons is a compilation album released by Kid Rhino on March 17, 1998. It contains musical highlights from all of the Nicktoons that had been produced up to that point (with the exception of Doug, as it had been bought and revived by Disney at that point). The theme song to the then-upcoming CatDog is listed as a "bonus track" on the back cover. Between the songs from each show, sound clips of Nickelodeon network spots are presented. The lyrics to each song are enclosed in the album's packaging. Confusingly, the printed lyrics do not specify which characters sing which lines.
