Johnny Test (partially found pitch pilot of animated TV series; 2004)
From The Lost Media Wiki
Johnny Test is an American-Canadian animated television series. The series revolves around the adventures of the title character, Johnny Test, an 11-year-old suburban boy who lives with his super-genius 13-year-old twin sisters, Susan and Mary, both of whom are scientists.
A pilot was produced in 2004, a full year before Kids' WB picked it up as a full series. Very little is known about the pilot, other than the fact that Johnny, Dukey (who was referred to as Poochie at the time), Mary, Susan and their parents, Hugh and Lila, all appeared in the pilot.
Only a screenshot from the pilot exists online. There is currently no video footage and screenshots other than the aforementioned.
