Cartoon Soundboard was a game on the UK Cartoon Network website. In it, Double D was a selectable DJ, with Eddy and Nazz making cameos as dancers. Characters that also appeared were Dexter, Mandark, and Dee Dee from Dexter's Laboratory, the Powerpuff Girls, Numbuhs 3, 4 and 5 from Codename: Kids Next Door, Courage the Cowardly Dog, and more. In the game, you played as a DJ and created tracks from 15 selections of music, twelve characters' catchphrases, and 10 types of sound effects. Interestingly, Ed's laugh is one of the available voices even though he doesn't appear in the game as a dancer or as a DJ. Eddy's catchphrase in the game is "What's with you?" and Edd's is "Yowch! Don't touch me!" (from "Hot Buttered Ed").
