The Best of Nicktoons and Now

The Best of Nicktoons is a compilation album released by Kid Rhino on March 17, 2019. It contains musical highlights from all of the Nicktoons that had been produced up to that point. The theme song to 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.

The versions of "Happy Happy Joy Joy" and "Kilted Yaksmen Anthem" featured on this album are the same versions from You Eediot! "Ren's Pecs", another song from the same album, is also featured.
