I found this as someone close to my family worked at Nickelodeon Animation, and specifically at DNA Productions, at the end of Jimmy neutron, and this was seen off an early master of "The Jimmy Timmy Power Hour 4", which would be cancelled right after the animatic was completely finished. DNA would soon thereafter strip itself down for parts during the next year.
anyways, this is from an early master of "The Jimmy Timmy Power Hour 4".
For some reason, The Omation logo was fully complete by 2005-06, but wouldn't be used until the end of the first season of Back at the Barnyard. and also the Billionfold logo would appear, too, which only appeared on Danny Phantom at the time.
