Ed, Edd y Eduardo

I remember reading the Wikipedia article for Ed, Edd n Eddy circa 2007, and it had a section for spin offs, other media or something of that nature. It mentioned an interstitial crossover short where Eduardo from Foster's Home for Imaginary Friends appeared in the cul de sac and interacted with the Eds. While almost anyone can put almost anything on Wikipedia, Cartoon Network used to be well known for its crossover commercials throughout much of its history (I think they mostly stopped after the "Cartoon Network City" era), and I've since found other references to it on some other sites, such as Reddit and Tumblr, which refer to it as "Ed, Edd y Eduardo," stating that Eduardo takes the place of Eddy. It even has its own article on Fandom's Ed, Edd n Eddy Wiki, and some say it was actually a series rather than just one short. Multiple people have tried to find it, with no luck. The Tumblr blog Party at Kevin's House claims it's just a bumper; a clip from a season 3 episode, possibly "Luck of the Ed," with Eduardo inserted over Eddy, and he's having language barrier problems (odd, because he speaks English just as well as Spanish, but whatever).
