The Backyardigans (partially found unaired pilot episode of CGI animated series; 2002)
A CGI-animated pilot episode for The Backyardigans (then titled Backyardigans) was produced in 2002. It was based upon another declined pilot from 1998 called Me and My Friends.
Little is known about the pilot, though some footage is found in a video that has since been deleted. Some screenshots do exist. Also of note is that Austin the Kangaroo seems to be completely absent, even from concept art.
